Design of X-band receiver on airborne SAR/GMTI multi-model reconnaissance radar

Research of synthetic aperture radar (SAR) for Moving target detection and imaging has huge value of military and civilian, a great many of countries are seeking to study motion detection and imaging technology, and to seek efficient and practical method and new system, especially to study the ground of moving target detection and imaging (SAR / GMTI) technology, With the development of airborne SAR radar system, its requirements not only the system size, weight and reliability continue to increase, but also dynamic and the radial resolution of the ground targets, This paper discusses the experiment situation of a receiving channel X-band of airborne SAR / GMTI multimode battlefield surveillance radar, the receiver channel adopt the technology of MMIC circuits micro-assembly and circuit embedded, it make breakthrough at the key technologies of multi-channel consistency and multi-mode, integration and miniaturization.
