Feasible Flight Paths for Cooperative Generation of a Phantom Radar Track

Electronic attack on air defense radar networks by a team of Electronic Combat Air Vehicles (ECAVs) is explored. The scope of the attack considered is the creation of a coherent phantom track in two dimensions—range and azimuth—by a team of coopera-tively controlled ECAVs, where each ECAV is capable of intercepting and sending delayed returns of radar pulses. Severe restrictions are shown when a constant-speed ECAV and constant-speed phantom track are assumed. Dynamic limitations on an ECAV are pre-sented mathematically and through simulation for straight and circular phantom tracks and specified ranges on the phantom target speed, ECAV speed, and ECAV region of an-tenna operation. Based on results for a straight or circular phantom track, generalized bounds for the initial conditions and time-dependent flyable ranges of a team of ECAVs are presented. These bounds are then used with coordination functions to formulate a decentralized cooperative control problem for the scenario of three radars versus three ECAVs generating a straight phantom track.
