【Abstract】 The techniques for moving target detection and clutter suppression in pulse Doppler radar are discussed based on the analysis of radar clutter characteristics.Illustrations for calculation of the relevant performance indexes are also given.Engineering practices show that by combining the large dynamic range linear receiver with the FFT digital signal processing technique,a higher improvement factor and a better performance of clutter suppression can be obtained.更多还原
