Introduction to monopulseradar
Monopulse radar is a precision tracking radar. Each time it emits a pulse, the antenna can form several beams at the same time, and compare the amplitude and phase of the echo signals of each beam. When the target is located on the antenna axis, the amplitude and phase of the echo signals of each beam are equal, and the signal difference is zero. ; When the target is not on the antenna axis, the amplitude and phase of the echo signals of each beam are not equal, resulting in a signal difference. The antenna is driven to turn to the target until the antenna axis is aligned with the target, so that the high and low angles and azimuth angles of the target can be measured. The sum of the signals received by each beam can measure the distance of the target, thereby realizing the measurement and tracking of the target.
