Concepts for Generating Coherent Radar Phantom Tracks Using Cooperating Vehicles

Abstract

Multiple cooperating Electronic Combat Air Vehicles (ECAVs) are used to generate phantom radar tracks in a multiple radar air defense network. The vehicles use a range delay deception transponder, which delays the radar pulses received by the ECAV and sends them back to the radar. This results in the radar calculating an erroneous target range. A radar network will correlate tracks to discern actual vehicle positions from phantom targets. The ECAV team, however, precisely positions and dynamically coordinates the motion of the vehicles so that all radars see the same phantom track. This paper presents twodimensional mathematical relationships between the motion of the vehicles and the motion of the phantom tracks. Closed form solutions are obtained for the ECAV trajectory given a specifled phantom track. Parametric analyses are performed with constraints on the overall vehicle dynamics, in which case ∞yable regions are established to ensure the integrity of the phantom target track. Results are presented for a single vehicle and a single radar engagement, and for up to four vehicles generating single and multiple phantom tracks for up to four radars correlating returns. This paper presents several concepts for generating phantom tracks using cooperating vehicles.
