Abstract:

Radar detection performance is related to target echo characteristics, and the detection probability of target can be improved by designing waveform frequency matching with the angular domain fluctuation characteristics of target. In this regard, a multi-radar waveform design algorithm based on heuristic frequency domain programming is proposed. In offline state, the angle frequency matching set for matching the characteristics of maneuvering targets is designed in three steps: angle domain division under fluctuation factor constraints, maximizing angle domain association with fluctuation factors, and abnormal angle domain decision-making. In the target tracking stage, the multi-station radar extends the detection frequency to optimize the angular domain. According to the filter predicted state value of maneuvering targets in the state transition region, the radar node and radiation frequency parameter programming under the condition of uncertain target echo is completed. Simulation results show that the detection performance of the proposed algorithm is significantly improved in the tracking scenario of alternating motion of uniform straight line and cooperative turning.
