面向机载雷达目标跟踪的脉冲重复间隔实时优化方法OA

In the target tracking process of airborne pulse Doppler radar,the optimization of pulse repetition interval(PRI)is difficult to satisfy the real-time requirements due to multidimensional ambiguity constraints and high computational complexity.In view of the above problem,this paper proposes a real-time PRI optimization method based on multidimensional folding constraints.By establishing a joint constraint model of range-Doppler folding and waveform blind zones,the complex non-linear optimization is transformed into the solution of analyti-cal intervals under a finite combination of folding times.For multitarget scenarios,the joint design is achieved by introducing the target merging within the beam and taking the intersection in the feasible region.Simulation re-sults show that the proposed method achieves microsecond-level computation under stringent engineering con-straints,significantly improving real-time performance compared with the traditional interval search method.This method has solved the online design problem of target tracking waveforms in complex environments,thus having strong engineering practicability.
