TransRAD: Retentive Vision Transformer for Enhanced Radar Object Detection
IEEE Transactions on Radar SystemsDespite significant advancements in environment perception capabilities for autonomous driving and intelligent robotics, cameras and LiDARs remain notoriously unreliable in low-light conditions and adverse weather, which limits their effectiveness. Radar

Radar Tomography For Cavities Detection
9th EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 1996Preliminary tests on laboratory models have enabled us to provide some guidelines for traveltime ray tomography with GPR applied to civil engineering problems, specifically to find voids in pillars, walls and structures. The width of the Fresnel zone and the source and receiver locations are the limits to resolution capability. For crosshole geometry a

RADAR DETECTION OF PRECIPITATiON
Journal of Meteorology, 1946Abstract Detection of precipitation by radar is possible because of the scattering of high-frequency radio waves by precipitation forms. Radar echoes being thus directly related to precipitation may be classified in a simple manner according to meteorological origin.

Radar Detection of Small Target in Sea Clutter Using Orthogonal Projection
IEEE Geoscience and Remote Sensing Letters, 2019Sea clutter submerges the small target echo, which is disadvantageous for radar target detection. In this letter, we propose to suppress the sea clutter by orthogonal projection (OP).

Compressive CFAR radar detection
2012 IEEE Radar Conference, 2012In this paper we develop the first Compressive Sensing (CS) adaptive radar detector. We propose three novel architectures and demonstrate how a classical Constant False Alarm Rate (CFAR) detector can be combined with l 1 -norm minimization. Using asymptotic arguments and the Complex Approximate Message Passing (CAMP) algorithm we characterize the ...

Target detection is a probabilistic idea; noise and clutter prevent us from being certain to find the targets we are looking for, and will normally present us with plenty of 'targets' we are not looking for. We can only define the probabilities of detection and of false alarm that we are prepared to live with.
