针对云团、消极干扰影响搜索雷达发现目标,在电路设计上采用了风速补偿技术,并对风速补偿设计原理、设计方法与结果进行了详细分析。对于跟踪雷达跟踪高速目标(卫星发射初段),回波信号脉压后存在时频耦合现象,引起距离走动。为了保证跟踪距离精度,采用了脉冲压缩速度补偿技术,消除距离偏差。通过实例与仿真分析,实现了跟踪距离精度要求。因此,采用风速补偿与脉冲压缩速度补偿设计,雷达发现目标与跟踪目标稳定可靠。

According to the clouds,negative interference effects found search radar target,circuit design using the wind speed compensation technology,and the wind speed compensation design principle,design method and the results are analyzed in detail.For tracking radar tracking high-speed target（satellite launch the opening）,echo letter feel the pulse pressure there after the time-frequency coupling phenomenon,cause the distance around.In order to guarantee the tracking accuracy of distance,the pulse compression speed compensation technology,eliminate the distance deviation.Through the examples and simulation analysis,realize the tracking range accuracy requirement.Therefore,the wind speed compensation and pulse compression speed compensation design,radar detected the target and tracking target is stable and reliable.
