基于脉冲块追赶的双基地雷达空间同步技术

为解决脉冲追赶技术在双基地雷达空间同步上的应用问题,提出了一种基于脉冲块追赶的双基地雷达空间同步技术,推导了脉冲块追赶时间表的计算公式,提出了以接收机波束形成速率为标准的工程可实现性分析方法,并对脉冲块追赶下的接收波束宽度和波束形成速率进行了仿真分析。仿真结果表明,在相同的双基距离积下,减小发射波束宽度、基线距离、发射脉冲宽度以及增大脉冲块长度可以降低对接收机波束形成的要求,便于工程实现。

A Spatial Synchronization Technology of Bistatic Radar Based on Pulse Block Chasing

In order to solve the problem of application of pulse chasing to bistatic radar in spatial synchronization,a spatial synchronization technology based on pulse block chasing is proposed.The calculation formulas of pulse block chasing timetable are derived.An analysis method of engineering feasibility,taking beam forming rate as standard is presented.Under pulse block chasing,the simulation analysis of receiving beam width and beam forming rate is made.The result of simulation analysis shows that,at the same bistatic distance product,reducing transmiting beam width,baseline distance,transmiting pulse width and increasing the length of pulse block width can reduce the demand of receiver in beam forming to implement easily in practice.
