The present invention is a two-stage distributed cooperative source positioning method based on pseudo-code
spread spectrum, which involves
radar detection technology, absorbs the advantages of distributed systems and
computer network systems, and realizes the
system's positioning search capture and positioning tracking functions separately, reducing the Difficulty in technical implementation. A method and technology for long-distance and high-precision detection of air, ground and sea targets is proposed by using cooperative pseudo-code
spread spectrum signals to construct a distributed detection
system. The present invention is not only different from the systems and methods of air target detection using the non-cooperative signals of terrestrial TV stations, radio stations and mobile communication base stations that have been developed at home and abroad, but also different from the passive positioning that uses the
radiation source carried by the target to achieve detection.
system. It can realize reliable detection of unconventional and conventional targets such as stealth aircraft,
cruise missiles, and ultra-low-altitude aircraft in a large area, which is of great military value.
