High-precision guiding method applied to photoelectric tracking system of vehicle-borne platform

Abstract

The invention discloses a high-precision guiding method applied to a photoelectric tracking system of a vehicle-borne platform, which is applicable to the photoelectric tracking system of the vehicle-borne platform, aiming at solving the problems of low guiding precision and even difficult guiding of the photoelectric tracking system due to the facts that the vehicle-borne platform is difficult to level with a high precision, and the state is not stable after leveling. A high-precision electronic gradienter is fixed on a plane which is vertical to a position axle, and the transverse direction of the high-precision electronic gradienter is tangent with the position rotating direction; data are transmitted to a computer by the high-precision electronic gradienter through a serial port in real time; guiding data of a target position are corrected in quasi-real time depending on measuring data of the high-precision electronic gradienter and an angle measuring element, and the error is corrected by the system to realize the high-precision guidance of the photoelectric tracking system of the vehicle-borne platform.

Description

technical field [0001] The invention relates to a high-precision guidance method for a vehicle-mounted platform photoelectric tracking system. Specifically, it is aimed at the low leveling accuracy of the vehicle-mounted platform. With the change of the external environment, the state of the vehicle-mounted platform is unstable and causes the vehicle-mounted platform photoelectric tracking system. The defect of low guidance accuracy or difficulty in correct guidance achieves a guidance accuracy comparable to that of ground-based photoelectric tracking systems, and is basically not affected by changes in the state of the vehicle platform. Background technique [0002] In order to quickly capture the target, it is often necessary to guide the photoelectric tracking system with higher precision. For the ground-based photoelectric tracking system, due to the stable state of the ground, the system error correction method can achieve high-precision guidance for a long time. At pr...
