Analysis on Missile-borne Bistatic Forward-looking SAR Imaging Perfomance

Synthetic aperture radar (SAR) has been gradually applied to missile guidance for its advantages of all-weather, all-time and long-distance capabilities. Nevertheless, missile-borne SAR can not image on the area in front of the missile track restricted by SAR working characteristics. Missile-borne forward-looking SAR will be realized through separated transmitter and receiver. Iso-range contours, iso-Doppler contours, ground resolution and azimuth resolution are used to analyze the performance of missile-borne bistatic forward-looking SAR, as to provide the theoretical basis for its application.
