摘　　要：脉冲追赶空间同步方式广泛应用于双基地雷达。详细分析了脉冲追赶空间同步误差的影响因素,进而分析了接收波束指向和宽度误差对接收功率的影响,导出了同步误差所引起的接收功率损失计算公式。对不同条件下的接收功率损失进行了仿真,仿真结果验证了理论分析的正确性。The space synchronization with pulse chasing is widely applied in bistatic Radar.The factor of inducing the error of space synchronization with pulse chasing is analyzed in detail.And then the influence of the error of receiving beam direction and beam width on the receiving power is discussed,and the equation of receiving power loss is derived which induced by the error of space synchronization.The receiving power loss is simulated in different conditions,and the result verifies the theoretical analysis.
