N2 - After studying the resource-limited platform where the frequencies of the transmitter and the receiver are non-coherent with an uncertain initial phase jitter in each transmitted pulse, the azimuth and elevation difference signal channels of a three-channel monopulse system are combined into a single difference channel, leading to the dual-channel monopulse system. Then, a reference channel is introduced and a reference signal based dual-channel monopulse angle estimation method is then proposed, where coherent accumulation can be achieved for this non-coherent working system after calculating the correlation between the echo signals and the reference signal, followed by the presented dual-channel monopulse angle estimation method. Compared with the traditional three-channel monopulse system, better estimation results can be obtained by the proposed solution without increasing the required resources (weight, size, and power consumption).
