Abstract： |
The invention relates to a wide-band radar figure method used the multi-emitter and multi-receiver frequency molecular signal. It includes the below process: 1. the M array unit of the radar emitter emit M frequency molecular band signal 2. the radar receiver is made up of N receiving array units which is set with M receiving channels matched to the M frequency molecular band signal, so it can get M*N channels of the echo signal 3. disposing the M*N channels of the echo signal and finishing the object detection then it composes the many echoes into the high resolution figure in the object location and the distance. The invention has decreased the need of the radar to the instantaneous bandwidth also the radar has the ability of the electronic scanning to complete the object detecting, tracking and figure. |
