Abstract: Guiding radar is used for detecting target and extracting the tracking information from the received signal as a missileborne sensitive component. After calculaing the target information, the messages are offered to missile borne computer. Since theconception of guiding radar is put forward, guiding radar has been developed for sixty years. The technique of guiding radar is goingto mature along with semi-active to active and continuous-wave to mono-pulse. In the paper the development status of guiding radaris being summarized. The typical tecniques and products are expatiated. The actual level and development trend of guiding radartecnique are analysised. On the base of it, the evolvement of guiding radar receiver structure is introduced. According to differentrequirement in different times, the guiding radar receiver undergo the development process from anti-inverse receiver to inversereceiver ,eventually to the trend of hardware anti-inverse and signal processor design flexiblely. On the base of introducing thedevelopment of receiver，the analysis and comparison of anti-inverse receiver with inverse receiver are proceeded. The keytechniques which needed to be resolved of anti-inverse receiver are put forward. The resolve of the key techniques are significant forimproving the ability of precision guidance.
