NEW APPROACH TO A MULTISTATIC PASSIVE RADAR SENSOR FOR AIR SPACE DEFENSE

A method to apply the latest technology in Global Navigation Satellite Systems (GNSS), in particular the U.S. NAVSTAR GPS (NAVigation System for Timing And Ranging Global Positioning System) and the Russian GLO NASS (GLObal'naya NAvigatsionnaya Sputnikovaya Sistema), as a silent m ultistatic or parasitic radar for air defense will be described. These satellite systems serving as navigational aids are well suited for lo w power radar applications due to the similarity and compatibility of the transmitted satellite signals with modern radar signals, such as s pread spectrum modulation and Pseudo Random Noise (PRN) codes. Prelimi nary flight tests with airships, jet and propeller aircraft, helicopte r, anti tank missiles and spacborne targets (MIR) to study effects hav e been conducted.
