Abstract: Radar system has many applications in the military and civilian fields; it is utilized for targets detection, obtaining the range, the direction, altitude and velocity (for moving target). These information can be extracted from target signal. Target effects on the transmitted signal, such effects are delayed and Doppler shift for moving targets. Generally, the development of radar systems and radar signal processing are always in progress and real radar systems are not always available for testing these developments. This work required computer simulators which are used to test the modification and development of these systems. In this paper, the two types of targets (moving and fixed) signals are simulated. In order to implement the target block, the transmitted signals and antenna location signals must be generated as inputs to target block. The target block is simulated using MATLAB Simulink, this block is designed by specifying the parameters of target block such as the velocity, range, azimuth of a target (direction), the direction of the target movement angle and wavelength. This block is tested for all different types of radars such as pulse radar, pulse compression radar, continuous wave radar and frequency modulation continuous wave (FM-CW) radar.
