DEVICE MEASURING RANGE Russian patent published in 1998 - IPC

FIELD: radar systems for search and tracking. SUBSTANCE: receiving antenna has first lobe faired in direction to lobe of transmitting antenna and second lobe turned along azimuth. Receiver has two channels connected through amplitude selectors and converters of signal duration to code to subtracter which output is connected to indicator through permanent storage. Single-frequency continuous unmodulated transmitter is connected to input of transmitting antenna rigidly coupled to drive and receiving antenna. EFFECT: range with use of proposed device is determined by single radiation of object which diminishes time of range determination. 2 dwg
