Abstract:

Aati-radiation missiles （ARM） have become serious threats to military radar. It is an extremely important and complicated research task for counteracting ARM. The problems of counteracting ARM system design are discussed in this paper. It is extremely important to discover ARM and give warning as early as possible.The dynamic range of a warning receivershould satisfy such requirement-D1≥σ1/σ2·σ1-radar section area of a plane, σ2-radar section area of ARM. This paper has also analysed the effect of two interference sources. Both the coherent interferences and incoherent interferences could cause the angle deviation of radar homing head of ARM.The formulas of angle deviation which could be caused by the interferences are given in this paper. How to set the interference sources is also discussed.

Key words: ew, eccm, radar, missile, anti-radar missile or anti-radiation missile
