Abstract

The invention provides a large inertia radar tracking method and system based on timing information fitting, and relates to the technical field of radar precision tracking. The method comprises the following steps: performing time synchronization processing to obtain absolute time of a servo subsystem, and then setting constraint conditions and key parameters of a seven-segment curve by using obtained target position related information; and then real-time seven-section curve fitting is carried out, an accurate smooth curve between the actual position of the current radar and the initial prediction position of the task is interpolated, and finally tracking control of the large-inertia radar is realized based on the accurate smooth curve servo subsystem. The purpose of large-inertia radar accurate tracking is achieved on the premise that the radar vehicle-mounted platform and the overall structure of a vehicle body are not changed.

Description

technical field [0001] The invention relates to the technical field of radar precision tracking, in particular to a large inertia radar tracking method and system based on time-statistic information fitting. Background technique [0002] Vehicle-mounted radar needs to take into account the high maneuverability and structural stability of the radar vehicle-mounted platform because it needs to perform fast and precise measurement and target identification of long-distance space targets. When the servo system of the vehicle-mounted radar adopts the traditional single PID control method, the initial angle of the input target and the angle position of the current servo will inevitably have random errors at the moment when the task starts or when a new task is switched during the task process, which is equivalent to directly affecting the system. When a step signal is input, the shock generated by the fast response of the large inertia radar turntable to the step signal is related...
