Radar servo system adaptive variable bandwidth tracking realization method

The invention relates to an adaptive variable bandwidth tracking implementation method for a radar servo system, and the difficulty of adaptive variable bandwidth implementation mainly comprises the setting of servo parameters and the construction of adaptive servo bandwidth switching criteria. The adaptive variable bandwidth tracking implementation method comprises the following steps: firstly, aiming at an II-type radar servo system, dividing according to Ka values; a phase margin maximum criterion is adopted to determine controller parameters of an auto-tracking loop, 5-6 groups of servo bandwidths are debugged, the stability of the servo bandwidths is judged by using the phase margin, then criterion construction and switching processes of radar servo adaptive bandwidth switching are introduced, and finally simulation analysis and test verification show that the stability of the radar servo adaptive bandwidth switching is improved. The method is high in adaptability, the bandwidth switching process is stab
