UWB active aperture synthesis radar the operating principle and development of the radar block diagram

The new algorithm of signal processing for building of high spatial resolution radar images is developed. A distinctive feature of this algorithm is the ability to form images of the area that is traditionally not viewable from aircraft and aerospace objects. This area approximates usually ±(20°...25°) from the aircraft's normal axis. In this angle sector the horizontal range resolution of radar images is low. The block diagram of complex radio engineering system that combines advantages of active radar and passive aperture synthesis systems is developed for obtaining of images with the acceptable spatial coordinate resolution in the angle sectors of observation.
