Target recognition is a challenging problem in air-to-surface terminal guidance for missile-borne millimetre wave radar (MWR). The class of high range resolution profile (HRRP)-based automatic target recognition approaches is sensitive to the attitude of target. One effective way to improve the performance of target recognition is acquisition of multidimensional information from target's image. Here, 2D ISAR imaging of the ground static target for the forward-looking missile-borne MWR is studied. The relative signal model and some key points are analysed. The effectiveness of the proposed approach is demonstrated by simulation and real data processing results.
