GPS bistatic radar using phased-array technique for aircraft detection

A study has been made into using a 32-elements phased-array receiver to detect the echo of GPS signals from a moving target. This paper mainly proposes the methods that improve the performance of GPS bistatic radar with phased-array receiver and allow it to properly perform aircraft detection. Among these methods are antenna array phase error calibration, array gain optimization and interference signal cancellation technique. Also, the detection technique of using PRN codes that are directly acquired by phased-array receiver is also proposed in this paper to search for the correlation of GPS signals.
