AI Technical Summary
Technical Problem
Existing radar detection methods suffer from signal energy divergence due to target motion when improving detection range and resolution, and existing technologies increase system complexity or cost.
Method used
Using spatial feature encoding signals with target spatial characteristics, narrow pulse signals are converted into microwave pulse signals for detection. Spatiotemporal compression technology is used to achieve instantaneous detection and differentiation of targets, eliminating non-specific targets.
Benefits of technology
It achieves instantaneous target detection, avoids signal distortion caused by changes in target state, improves radar detection range and target discrimination capability, and reduces the impact of time-varying signals.

Abstract
本发明公开了一种基于空间特征信息的时空压缩雷达探测方法及系统，属于雷达探测技术领域。该方法将目标的空间特征信息转换成具有一定长度的脉冲回波信号，再将脉冲回波信号进行时域反转编码处理，得到空间特征编码信号。空间特征编码信号经过天线辐射后，与目标相互作用，形成时空压缩效应，在时域表现为目标的反射信号为一个脉冲宽度变窄的窄脉冲，信号的峰值功率得到大幅度提升。对于不匹配的目标，空间特征编码信号无法与之形成空间压缩效应，目标的反射信号无法实现时空压缩形成窄脉冲，从而有效实现了雷达对目标的区分能力。
