Abstract: An adaptive high resolution forward-looking imaging strategy for missile-borne millimeter detector is proposed for satisfying the combat mission of new generation optional burst height proximity fuze. The accuracy of azimuth angle estimation can be dynamically improved by processing the intercepted echo signal data in a distance zone, thus obtaining the more accurate azimuth information of targets, and generating the azimuth-range image of target. The proposed imaging strategy has broken through the traditional monopulse angle estimation method which uses the ideal azimuth curve to estimate the actual angles of different targets. The algorithm uses the actual echo signal data to modify the error generated by angle curve in real time to ensure the high estimation accuracy in azimuth direction. The experimental results show that the proposed imaging algorithm is used to obtain the optimal resolution angle curve in thesame range after 8 times iterative calculation, and achieve adaptive focusing in azimuth direction. Compared to traditional imaging strategy based on real beam scanning technology, the proposed imaging strategy based on monopulse imaging improves the azimuth resolution about 10 times. And the complexity of the algorithm also meets the requirement of missile platform. Key
