Removing micro-motion clutter effectively is critical to improving radar performance. In this study, a micro-motion clutter removal method based on the cancelation of the Short-Time Fourier Transform (STFT) spectrogram is proposed using the difference in the morphological performance of the constant-...
Compared with traditional phased array radar, Ubiquitous Radar does not require beam scanning, offering longer accumulation time and higher Doppler resolution, which enables the effective separation of LSS targets from clutter. The high-resolution Doppler provides more refined Doppler features for target ...
Figure 8. Spectrogram of background clutter (top) and Mavic Air 2 (bottom). The red box is the non-recorded section of the target. In the spectrogram of Mavic Air 2 on the right, the red box is non-recorded sections because of the target’s low signal intensity. When these non-rec...
