| Abstract: Radio seeker in a semi-active homing guided missile system is a crucial subsystem for performance analysis and development. The signal at the front and rear receivers are mixed to shift the carrier frequency to an intermediate frequency (IF) where the target’s Doppler shift can be detected. Such a system has various sources of uncertainties that may significantly affect the radio seeker ability to detect a target correctly including noise, clutter, jamming, and target maneuvers, etc. Uncertainties may lead to degrade the performance of a CW Doppler Monopulse seeker. This paper investigates a semiactive homing missile guidance and control system in presence of jamming, noise and uncertain target maneuvers. In particular, the paper introduces an Electronic Counter Counter-measurements (ECCM) technique that degrades the effectiveness of blinking jamming (BJ) and multiple blinking jamming (MBJ) techniques. These two selfscreening ECM techniques are sources of incoherent deception, where they attempt to attack the tracking dynamics of the angle-tracking radar and, hence, may be effective against some types of Monopulse radar as well as other tracking radars. A mathematical model of a typical Monopulse tracking seeker is presented. A three-degrees-of-freedom missile-target engagement simulation model is carried out under MATLAB/SIMULINK environment for testing and evaluation. Simulation results are given. The paper is terminated with conclusions. | ||||
