This paper was prepared to be acquainted with the effect of parasitic elements on the faulty antenna performance with respect to the performance of healthy antenna without directors. This work interested in two models of microstip antennas, the first consists of four elements without directors and the second is an antenna with three directors as parasitic elements. The antenna was designed and simulated...
When the radar transmits electromagnetic waves, the target characteristics can be extracted from the received echo signal. During the reception process, the radar carrier frequency will be shifted due to the Doppler effect of moving targets. If a specific target makes any vibration or rotation, an induced frequency modulation on the received echo signal will be occurred generating side-bands around...
