In this work a plane wave is used to localize a point target and in addition to speeding up the imaging scenario rather than moving the antenna to synthesize the long aperture as done in conventional SAR instead of moving the antenna to synthetize the long aperture a single plane wave transmitter and a linear passive antenna array for the receiver are used. Single plane wave transmitter in far field is considered as an abundance of narrow beam width along a line parallel to the target. Transmitter antenna illuminates the target in all positions directions that the radar used to move in SAR technique. The Linear array is put in a closer distance to the target and collects the back scattered field coherently in a several positions. This collection will be considered as a strip map SAR mode. The proposed technique is implicitly the same as SAR technique. The SAR standard imaging image processing, back projection algorithm is used to construct the image. Since the proposed technique transmits a plane wave for a single time and the linear array collects data in all positions simultaneously, the speed of this technique is considerably more than the conventional SAR تفاصيل المقالة
