摘　　要：末制导雷达作为弹载敏感部件,用来检测目标、从接收信号中提取跟踪数据,并计算出目标信息提供给弹上计算机。从1944年末制导雷达这一概念的首次提出到如今,末制导雷达已经历了六十多年的发展,末制导雷达技术从半主动向主动、连续波向单脉冲不断完善。本文对末制导雷达技术的发展情况进行综述,阐述了在末制导雷达技术发展各个阶段的代表技术和典型型号,分析了末制导雷达技术的现有水平和发展趋势,在此基础上,特别介绍了末制导雷达接收机结构的演变,根据每个时期的不同需求,接收机经历了从非倒置接收到倒置接收,最终向硬件非倒置,信号处理机灵活设计的趋势发展的过程。本文在理清接收机结构设计发展脉络的前提下,开展了倒置接收机和非倒置接收机两种末制导雷达接收系统的性能分析与比较,提出了非倒置接收机在发展中需要解决的关键技术。这些关键技术的解决对于提高末制导雷达精确制导能力至关重要。Guiding radar is used for detecting target and extracting the tracking information from the received signal as a missile borne sensitive component.After calculaing the target information,the messages are offered to missile borne computer.Since the conception of guiding radar is put forward,guiding radar has been developed for sixty years.The technique of guiding radar is going to mature along with semi-active to active and continuous-wave to mono-pulse.In the paper the development status of guiding radar is being summarized.The typical tecniques and products are expatiated.The actual level and development trend of guiding radar tecnique are analysised.On the base of it,the evolvement of guiding radar receiver structure is introduced.According to different requirement in different times,the guiding radar receiver undergo the development process from anti-inverse receiver to inverse receiver,eventually to the trend of hardware anti-inverse and signal processor design flexiblely.On the base of introducing the development of receiver,the analysis and comparison of anti-inverse receiver with inverse receiver are proceeded.The key techniques which needed to be resolved of anti-inverse receiver are put forward.The resolve of the key techniques are significant for improving the ability of precision guidance.
