Get this from a library! MTI and pulsed doppler radar with MATLAB. m’ and ‘plot_brown. A monostatic radar consists of a transmitter colocated with a receiver. Change the antenna's height to 100 meters to simulate a radar mounted on top of a building. The transmitted signal and the received echo signal are mixed in a detector to get the Doppler shift and the difference signal is filtered using a Doppler filter where the unwanted noise signals are rejected. The magnitude of the radar signal at the antenna during the transmit and receive durations are depicted in succession in Figure 5. The radar receiver for this system can also function as an EW receiver. Each chapter includes the mathematical and analytical coverage necessary for obtaining a solid understanding of radar theory.
