Null Function as a Fast and Accurate Algorithm for Noisy Environment Target Detection in PCL Radars

A new fast and very accurate algorithm for target detection in PCL (passive coherent location) radars is presented. This algorithm in noisy environment that SNR is low as -45 dB operates, with an error less than 20 percent. Presented algorithm is capable for target detection by few samples of signals and obtains real-time processing in passive radars
