Abstract

The invention relates to a method for tracking MEO / LEO satellites, relates to the field of computer software and photoelectric tracking, and solves a problem of target loss caused by unstable extraction of faint target miss distance in a conventional optical tracking process. The method comprises acquiring target tracking measurement data according to guidance rotary table orientation pitch data fed back by a servo control system and target miss distance data fed back by an image processing system; determining whether a deviation value between the obtained target tracking measurement data and the current frame data is within + / - 3[sigma]; if not, determining that the tracking data is invalid, extrapolating the current frame data, and using the extrapolated current frame data as valid data; if so, determining that the tracking data is valid, extrapolating the next frame data by using the recorded valid data, and sending the extrapolated next frame data to the servo control system to guide the rotary table for continuous tracking until the end of the tracking process. The method provides complete and reliable measurement data for tracking measurement to the utmost extent.

Description

technical field [0001] The invention relates to the field of computer software and photoelectric tracking, in particular to a tracking method for medium and low orbit satellites. Background technique [0002] With the advancement of science and technology, satellites, as an important means of obtaining various information and the main source of collecting important intelligence, are constantly favored by countries. At the same time, the tracking measurement, maintenance and control of satellites has become a new research focus. Due to its high-precision tracking and measurement capabilities, photoelectric measurement equipment has become an important tool for satellite tracking and measurement. [0003] At present, the domestic satellite tracking and measurement process mainly includes obtaining satellite forecast data, guiding the equipment to capture the target, and when the satellite enters the field of view of the equipment, it starts to capture the target, switches the...
