Study on bistatic (multi) radar system using navigation satellites

The operational principle of passive detection radar based on outer radiation source is introduced. Based on the in-depth research study on operational principle of non-cooperation bistatic(multi) radar and the requirement for air target detection especially stealth target detection, a space-ground bistatic(multi) radar system based on navigation satellite signal is presented. The paper has analyzed the feasibility of target detection using navigation satellite signal and the problems for system function realization. The system operational principle and detection performance has also been studied.
