-
Presents the development of modern signal processing techniques, a new implementation method which realizes quadrature coherent detection by direct sampling of if signal generated during the implementation of traditional quadrature coherent detection with analog elements in the form of two parallel baseband channels where in phase ( i ) and quadrature ( q ) components of ceived if singnal where, the imperfect matching of the separate channels due to the analog elements results in high phase and amplitude which meets the needs for high performance radar signal processing, the elementary principles and the implementation process for each method and concludes from simulation results to compare their features and application conditions that the new approach can satisfy of the requirements of high performance sp
