基于物理约束的空气耦合探地雷达早时响应分离方法
By setting antenna parameters and excitation signals, an early response time window is established. By using a dual-transmitter single-receiver antenna system to suppress direct waves and ground-reflected waves, the problem of difficult-to-distinguish early response signals in air-coupled ground-penetrating radar systems is solved, and high signal-to-clutter ratio and stable detection of shallow targets are achieved.

AI Technical Summary
Existing air-coupled ground-penetrating radar systems lack systematic physical modeling in early response signal processing, making it difficult to distinguish direct waves, surface reflected waves, and underground target echoes in the time domain, affecting the detection effect of shallow targets. Furthermore, existing clutter suppression methods rely on empirical parameters, making it difficult to maintain stability and effectiveness.
The physical constraint-based air-coupled ground-penetrating radar early response separation method establishes an early response time window by setting antenna parameters and excitation signals, and uses a dual-transmitter single-receiver antenna system to suppress direct waves and ground-reflected waves, thereby achieving effective separation of the early response.
It enables quantitative discrimination of early response in air-coupled ground-penetrating radar systems, improves the resolution and detection stability of shallow targets, reduces the masking effect of strong ground reflection and direct coupling on shallow target echoes, and enhances the signal-to-clutter ratio and detection reliability of the system.
