摘　　要：天空双基地预警雷达由天基发射端与空基接收端组合而成,其空间同步问题是该型雷达正常工作的前提,为此开展天空双基地雷达空间同步技术的研究。首先,介绍了脉冲追赶同步技术的原理并详细推导了相关的控制参数计算公式;然后,为解决传统脉冲追赶空间同步技术存在的空域覆盖矛盾和波束驻留时间矛盾,有针对性地提出了两种多波束脉冲追赶的解决方案;最后,通过一个具体场景下的同步实例对脉冲追赶同步技术的可行性进行了仿真验证。Space-air based bistatic early warning radar consists of the air-based transmitter and the space-based receiver.The spatial synchronization technology is a prerequisite for normal operation of this kind of radar,so it is necessary to carry out the research about the spatial synchronization technology of space-air based bistatic early warning radar.First,the principle of pulse chasing synchronization technology is introduced and the calculation formulas of relevant parameters are derived.Then,in order to solve the contradictions of airspace coverage and dwell time of traditional pulse chasing spatial synchronization,a multi-beam pulse chasing technology is proposed.Finally,the simulation is performed to verify the feasibility of this pulse chasing synchronization technology.
