JSC services are available on-site at Army field commander locations worldwide. e. The JSC provides services to Army agencies on a cost reim- bursable basis. f. Army organizations requesting spectrum management support or analytical services pertaining to existing or anticipated EMC problems should address their requests to the Commander, JSC, ATTN: AR, 120 Worthington Basin, Annapolis, MD 21402-5064, DSN 281-2103, Commercial (410) 293-2103, facsimile (410) 293- 2631.
(2) USASC is responsible for the dispatch of monitoring and DF teams to the affected site within 24 to 72 hours. (3) AMC will maintain a database of spectrum interference inci- dents reported to HQDA/USACESO. c. The procedures for reporting incidents of spectrum interference to Army forces located within CONUS are: (1) CONUS-based Army forces involved with sustaining base o p e r a t i o n s w i l l r e p o r t s p e c t r u m i n t e r f e r e n c e t o t h e s u p p o r t i n g DOIM, who will make every effort to resolve problems locally within the installation/MACOM-owned assets.
(2) If the spectrum interference cannot be resolved locally, the supporting DOIM will report the problem to the supporting DoD AFC as depicted in Figures B-1 and C-2. (3) If the AFC cannot resolve the problems regionally with other federal agency field offices (e.g., FCC, Federal Aviation Adminis- tration (FAA) Regions), the AFC will request the spectrum manager submitting the spectrum interference report to resubmit the spectrum interference report through command channels. d. The procedures for reporting incidents of spectrum interfer- ence to Army forces located OCONUS are:
(1) Army forces stationed OCONUS will report spectrum inter- f e r e n c e t o t h e s u p p o r t i n g J o i n t F r e q u e n c y M a n a g e m e n t O f f i c e (JFMO) in accordance with the guidelines contained in FM 24-35-1 and the JSIR Program. When required, reports may also be submit- t e d t o t h e s p e c t r u m m a n a g e r s s u p p o r t i n g A r m y c o m m u n i t y commanders. (2) Most instances of spectrum interference will be resolved lo- cally with the Division and Corps.
For those incidents of spectrum interference which cannot be resolved at echelons below Corps, a report will be sent to the Theater Army/CINC Joint Frequency Management Office (JFMO) headquarters for resolution. Where re- quired, the JFMO will interface with the host nation through the Status of Forces Agreements. (3) In cases where the JFMO cannot resolve the spectrum inter- ference problem, Army users will submit reports to HQDA, ATTN: SAIS-PAS-M (The Army Spectrum Manager) and the USACESO. A r m y u s e r s m a y a l s o b e r e q u i r e d t o r e p o r t t o o t h e r a c t i v i t i e s through existing CINC directives.
(4) Interference to high frequency (HF), satellite, or troposcatter communications may involve reporting the interference to activities outside the Theater/CINC area of responsibility. e. Incidents of harmful interference, whether occurring within CONUS or OCONUS, which cannot be resolved locally or regional- ly, may cause a serious threat to life or limb (i.e., interference to air traffic control, detonation of fuses to explosives, etc.); or may cause high-cost expenditure to the Army (e.g., delay or cancellation of a test), and therefore should be reported through Army interference resolution organizations (see Figure C-2).
Action will be initiated by these offices to coordinate resolution of the interference problem with appropriate Army activities. 3–7. Deconfliction a. Deconfliction is a systematic management procedure to coordi- nate the use of the electromagnetic spectrum for operations, commu- n i c a t i o n s , a n d i n t e l l i g e n c e f u n c t i o n s . I t i s a n e l e m e n t o f electromagnetic spectrum management. b. Deconfliction is comprised of three categories. They are: (1) Friendly communications equipment interfering with friendly e l e c t r o n i c s u p p o r t ( E S ) e q u i p m e n t ( i n t e r f e r i n g w i t h i n t e r c e p t operations).
(2) Friendly EA equipment interfering with friendly C-E equip- ment (jamming missions interfering with normal C-E operations). ( 3 ) H o s t i l e E A e q u i p m e n t i n t e r f e r i n g w i t h f r i e n d l y C - E equipment. c . T h e A r m y S p e c t r u m M a n a g e r s h a l l a d v i s e t h e A R S T A F , MACOMs, and other Army organizations of trends in very high power emitters as a result of its coordination at Joint, national, and international levels; and, with awareness of the susceptibility levels identified by the E3 program, ensure that the spectrum management process disseminates appropriate alerts and coordination. d.
To accomplish deconfliction, Army battlefield spectrum man- agers continually coordinate the assignment of frequencies to battle- field systems to minimize electromagnetic spectrum conflicts or interference with the IEW units of friendly forces. e. Information on the development and availability of automated deconfliction tools is available from the USACESO/(SAIS-PAS-M), DSN 227-0199. 3–8. Army Interference Resolution Program (AIRP) a. The AIRP revolves around four functions: (1) Direction Finding (DF). A DF capability is often the key to locating the source of interference and is an integral part of resolv- ing and analyzing incidents and problems.
The degree of accuracy is dependent on the environment and frequency band. (2) Signal Monitoring. Signal monitoring or spectrum surveil- lance incorporates a frequency spectrum analyzer or surveillance receiver covering all spectrum bands of use. These systems perform real-time evaluation of spectrum usage and interference in a specific area. (3) Signal Analysis. Analysis of DF and monitoring data is re- quired to determine the source of interference and misuse of the spectrum. ( 4 ) T r a n s p o r t a b i l i t y / M o b i l i t y .
D e g r e e , c i r c u m s t a n c e s , a n d geographic location of the types of interference incidents and prob- lems will determine transportability and mobility requirements. Mo- bile/transportable DF and monitoring equipment is a requirement for tactical units, training areas, and for incidents not necessarily con- f i n e d t o a s p e c i f i c g e o g r a p h i c a l a r e a . M a n p o r t a b l e e q u i p m e n t should also be considered for certain instances and conditions. Fixed equipment would be required for those areas which require real-time solutions in a defined geographical area. b. Responsibilities.
(1) The Army Spectrum Manager is responsible for reporting and coordinating the resolution of serious incidents of spectrum interfer- ence with appropriate HQDA and other Service activities, to include US civilian telecommunications organizations and host nations, if required. 3–9. Army E3 Objectives Relating to Spectrum-Dependent Devices a. The Army E3 objectives that relate to spectrum-dependent devices are: (1) To achieve EMC for all spectrum-dependent equipment oper- ated by the Army components. (2) To attain built-in design compatibility, rather than achieve EMC through the use of planned product improvements (PPI) after development.
(3) To promote EMC philosophies and techniques in the acquisi- tion and use of spectrum-dependent equipment. (4) To promote total EMC test and analysis techniques of all systems with spectrum-dependent materiel. b. Detailed procedures for implementing the Army E 3 Program are contained in Army Acquisition Executive (AAE) Policy Memo- randum 91-3. 12 AR 5–12 • 1 October 1997
