中文说明： LFM信号在脉冲压缩体制雷达中广泛应用；利用线性调频信号具有大带宽、长脉冲的特点，宽脉冲发射已提高发射的平均功率保证足够的作用距离；而接受时采用相应的脉冲压缩算法获得窄脉冲已提高距离分辨率，较好的解决了雷达作用距离和距离分辨率之间的矛盾；。而利用脉冲压缩技术除了可以改善雷达系统的分辨力和检测能力，还增强了抗干扰能力、灵活性，能满足雷达多功能、多模式的需要。
English Description：
LFM in widely used pulse compression radar signal using linear frequency-modulated signal with a large bandwidth, the characteristics of long-pulse, pulse launch has increased average power to ensure sufficient distance and accept the pulse compression algorithm is used when access to the pulse has been raised from resolution and better solve the contradiction between the radar range and range resolution. Using pulse compression technology to be able to improve radar resolution and detection capabilities, enhance anti-interference ability, flexibility, can meet the needs of multifunctional, multi-mode radar.
