An improved method of monopulse estimation in PD radar

Monopulse estimation is an angle measurement method with high data rate, measurement precision and anti-jamming ability, since the angle information of target is obtained by comparing echoes received in two or more simultaneous antenna beams. However, the data rate of this method decreases due to coherent integration when applied in pulse Doppler (PD) radar. This paper presents an improved method of monopulse estimation in PD radar. In this method, the received echoes are selected by shift before coherent integration, detection and angle measurement. It can increase data rate while maintain angle measurement precision. And the validity of this method is verified by theoretical analysis and simulation results.
