Abstract

Abstract

A novel approach of Ground Moving Target Indication (GMTI) based on subaperture is proposed in this paper. In this approach, the aperture of an antenna is divided into two subapertures. When the radar is in operation, the two subapertures pass the same ground patch in tandem with an interval of half of synthetic aperture time. During this interval, the position of a stationary target keeps unchanged, but that of a moving one is altered. Then, the moving target is detected by comparing images derived from the two subapertures, and its motion parameters can be estimated with its trajectory. In order to avoid the moving target being smeared and preserve its trajectory, azimuth focusing process is omitted. Compared with present GMTI approaches, the new one has many advantages, only single channel antenna, low cost, less computation load, compatible with SAR mode, etc.
