Synthetic aperture radar guidance system and method of operating same

摘要: A synthetic aperture radar guidance system adapted for use in a guided missile is described wherein the frequency of transmitted pulses changes with time chirp slope which varies range. The between also as function desired values and interpulse interval are computed all within range interest stored. Furthermore, operating parameters SAR changed changes. intervals frequencies selected to avoid interruption ambiguities eclipsing. phase synthesized signal controlled adjust motion vehicle on mounted. operated several modes. In search mode, beam steered across mapping area form plurality patches area. combined into one map entire Each pixel compared target template until match provided. Then operates track mode correlation process ensures toward using provided known feature data.
