Abstract

This paper investigates the detection performance of densely unmanned aerial vehicle (UAV) group on the air defense radar. The keystone is that multiple UAVs frequently fly in adjacent range resolution cell and usually locate in the same beam cell that inevitably has influence on the angle resolution capability of tradditional radar. Firstly, the monopulse angle estimation of unresolved targets is presented, this is inherently the classic dual source jamming model. Sencondly, to show the merging phenomenon of angle estimation, the probabilty density distribution related to multiple observations and different Swerling targets is given. Finally, a simulation involving parallel, cross and random flight trajectories on the detection performance of radar is given. It is found that when the number of UAV increases, or the spatial distribution of UAVs becomes denser, the probability of measurement merging increases. It is also found that if the beam width of radar increases, or the bandwidth of the radar signal decreases, the probability of measurement merging increases.
