At present, radar stations with digital synthesis of antenna aperture have received wide practical application over the world. When solving the problems of remote sensing of the surface and recognition of radar targets, such radars make it possible to obtain the radar image with high resolution in range and azimuth, in real time, at any time of the day and night, under various weather conditions. At the same time, if you use the methods of radio polarimetry, you can significantly expand the scope and functionality of these radars.
When the radar image by the «fast convolution» method is receiving in the radar station with digital synthesis of the an-tenna with a full polarization reception, it is necessary to calculate in real time the samples of the discrete Fourier transform of the trajectory signal and the reference function.
The article presents fast algorithms for obtaining samples of the discrete Fourier transform under quadrature signal processing with a full polarization reception (Cooley–Tukey algorithm, Rader algorithm). The efficiency of the fast algorithms is es-timated.
