3D imaging of moving targets for ultra‐wideband MIMO through‐wall radar system
IET Radar, Sonar & Navigation, 2021 Ultra‐wideband (UWB) radar is widely used in static through‐wall imaging (TWI). There are still many imaging problems of motion through‐wall targets for complex system structure and unknown wall environment.

TARGET DETECTION FROM MICROWAVE IMAGING BASED ON RANDOM SPARSE ARRAY AND COMPRESSED SENSING [PDF]
Progress In Electromagnetics Research B, 2013 This paper proposes an imaging scheme using a random sparse array (RSA) structure for radar target detection using compressed sensing (CS). The array collects sparse measurements with less collection time and data storage. Two schemes of the RSA are considered, random SAR mode and random array mode.

Research on Resolution of Terahertz Coded-aperture Imaging
Leida xuebao, 2018 Terahertz coded-aperture imaging follows the basic principles of optical coded-aperture imaging and microwave coincidence imaging and is a novel imaging technique. Herein, the wave spatial distribution or illumination pattern is usually obtained by a sub-
