弹载合成孔径雷达制导技术是合成孔径雷达(SAR)技术和精确制导技术相结合的一个高新科技,是提高精确打击目标的重要方法。文中介绍了国外SAR制导技术的最新发展,如调频连续波、单脉冲三维成像、多模复合制导雷达技术的应用,指出高速图像处理、高效算法及轻型低功耗等是未来精确制导技术的发展重点;综合分析了在研发SAR制导技术的工作中需要解决多项成像技术内容,最后指出为适应精确制导武器性能的不断提高,弹载SAR制导技术需要注意修正和完善之处,以提高对要害部位的打击。

Missile-borne SAR guidance technology is a high-teeh combination of synthetic aperture radar （SAR） and precision guidance technology and is an important method for improving target strike precision. In this paper, latest development of foreign SAR guidance technology is reviewed, such as FMCW SAR, mono-pulse 3D imaging radar and multi-mode composite guidance radar technology, high-speed image processing, new effective algorithm, then light-weight, low power consumption are pointed out as the key fields in future precision guidance technology. Some imaging issues that should be solved in R＆D of SAR guidance technology are analyzed. Finally, it is pointed out that missile-borne SAR guidance technology should evolve in some respects to enhance performance of precision guidance weapons and to improve the strike effect on vital hostile properties.
