Abstract: Now, the research on the MMW wideband phased radar seeker technology is very hot in many countries. The radar seeker’s deterrent force depends on its abilities of agility, long distance detection, precision guidance, and multi-target detecting. The MMW wideband phased radar seeker has agile beam scanning, can tracking the target precisely with the MMW imaging technology; also because of the active phased array, the seeker can get more controlled power to increase the detection distance and tracking multi-targets simultaneously. This paper firstly analyses the research status and the advantages of the MMW wideband phased radar seeker technology, then on the basis of the analysis, mainly in this article the technologies of the active array antenna, the MMW wideband imaging, the space-time adaptive processing, the multi-target detecting and tracking and so on are discussed.
