Real-time pulse repetition interval optimization method for airborne radar target tracking
摘要
Abstract
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.关键词
