Method for detecting and locating target by bistatic radar, involves calculating ratio of respective lines of frequency spectrums, and extracting bistatic distance of target by performing Fourier transform of ratio
The method involves performing a spectral analysis of a direct TV signal to obtain a frequency spectrum (10a), and performing a spectral analysis of a backscattered TV signal to obtain another frequency spectrum (10b). A normalization of lines of the latter spectrum is performed (20), and a ratio of each line of the latter spectrum to that of the former spectrum is calculated. A bistatic distance of the target is extracted (30) by performing a Fourier transform of the ratio, and a distance (L) and an angle (theta) of the location of the target is derived (40) from the bistatic distance.
