Target movement simulation for testing monopulse radar

Fast moving target simulator is required for testing the performance of monopulse radar. This paper deals with an electronically controlled phased array for the simulation of a fast moving target. A scheme consisting of four horn antennas with a precision attenuator (0.25 dB step) and 4 bit phase shifter is suggested, which will cover /spl plusmn/5.5/spl deg/ with a 10 mrad resolution at a distance of 9 m.
