Abstract
- Towed decoy can simulate the time domain and frequency domain characteristics of target in radar beam and form effective angle deception. In order to improve the radar ability to countermeasure towed decoy, this study extracts and uses the radar diagonal difference channel in the conventional monopulse radar. The characteristic of diagonal difference channel is analysed. Then, the equations of sum channel, azimuth difference channel, elevation difference channel, and diagonal difference channel are established. By solving the equations, the angles and amplitude of decoy and target are obtained. Decoy recognition method is proposed. The new method can obtain the angles of decoy and target using only one pulse, and recognise decoy steadily using several pulses. The simulation results confirm the effectiveness of the new method.
