Abstract

A frequency-scanned microstrip leaky wave antenna (MLWA) is combined with a short-pulse radar to achieve real-time range-azimuth imaging of a scene. The antenna is designed to have a narrow scanning beam across the bandwidth of the radar. The direction-finding capability is verified through measurement and full-wave simulation. An imaging algorithm based on the short-time Fourier transform is developed. Line-of-sight and through-wall images of a moving human are presented to demonstrate the performance of the system.
