A digital ASIC implementation of a video filter for synthetic aperture radar
[1991] GaAs IC Symposium Technical Digest, 2002Two GaAs ASICs have been designed and implemented for a synthetic aperture radar which eliminate the DC bias in the sampled video data and increase the signal to noise ratio by summing the data across consecutive bursts. The high-pass filter and presummer ASICs process data at a maximum sample rate of 170 MHz and 125 MHz respectively.

Lightweight and Accurate Video Synthetic Aperture Radar Target Detection Network
Photogrammetric Engineering & Remote SensingVideo synthetic aperture radar (SAR) target detection has seen rapid development in recent years, but current methods generally suffer from high computational complexity as well as frequent false alarms and missed alarms. Additionally, in video SAR scenarios, small targets become more difficult to identify due to low resolution and complex backgrounds.

The motion of targets is well known to result in their defocussing and displacement in SAR imagery, but detection of motion and re-focussing of targets under generic conditions remains of ongoing interest. One class of methods involves forming images of sub-apertures in which motion defocussing will be reduced. In this paper, we use dynamic tomographic
