摘要
讨论了配备空中平台的双基地雷达的空间同步问题。首先限定空地双基地雷达实现空间同步时的约束条件,给出了空地双基地雷达在特定工作模式下实现空间同步的方法;然后详细分析了空地双基地雷达在采用脉冲追赶和数字波束形成相结合的方法实现空间同步时的误差来源,推导出参数计算公式,并对其中的距离估值测量误差和脉冲追赶误差进行了仿真、讨论,从理论上验证了脉冲追赶和数字波束形成相结合的方法在空地双基地雷达中实现空间同步的可行性。
The problem of spatial synchronization is discussed in a kind of bistatic radar with airborne transmitter.At first,the constraints are given during realizing spatial synchronization in the air-ground bistatic radar.The method to realize spatial synchronization at the specific operation mode is proposed.Then error sources are analyzed in detail when the system uses a method,which combines pulse chasing and digital beam forming,to realize spatial synchronization.And the calculation equations of parameters are derived.At the same time,simulations and discussions on the measurement error of the distance estimation and the error of pulse chasing are carried out.The feasibility of the proposed spatial synchronization method using in the air-ground bistatic radar is verified in theory at last.
