脉冲压缩雷达能同时提高雷达的作用距离和距离分辨率。这种体制采用宽脉冲发射以提高发射的平均功率，保证足够大的作用距离；而接受时采用相应的脉冲压缩算法获得窄脉冲，以提高距离分辨率，较好的解决雷达作用距离与距离分辨率之间的矛盾。(Pulse compression radar can simultaneously increase the range and range resolution of the radar. This system uses wide pulse emission to increase the average power of the emission to ensure a sufficiently large working distance. When receiving, the corresponding pulse compression algorithm is used to obtain a narrow pulse to improve the range resolution, and better solve the radar range and distance resolution.
