AI Technical Summary

Technical Problem

Existing microwave telemetry methods result in target search failures, low measurement accuracy, and lack of visualization, which affects the progress of subsequent missions.

Method used

A composite telemetry method is adopted. After establishing a telemetry link using microwave telemetry equipment, the target is acquired and tracked through photoelectric telemetry equipment. Imaging is performed using short-wave and medium-wave dual-band imaging with a common optical path design to record the infrared radiation characteristics data of the target.

Benefits of technology

It enables precise target search and measurement, improves the reliability of telemetry data, and allows for visualization, overcoming the problems of poor real-time performance and system complexity in traditional telemetry, and improving task scheduling efficiency.

Abstract

The application provides a composite telemetry method, comprising the following steps: step one, target telemetry link establishment is carried out by using a first telemetry device, after the link establishment is completed, spatial target position solution is realized, a first position range is obtained, a value is sent to a microwave measuring device in real time, and a turntable is controlled to keep stable tracking on the target and keep the telemetry link stable; step two, a second telemetry device automatically captures and tracks the target in the first position range, and a second position range is obtained, wherein the area of the second position range is smaller than that of the first position range; step three, on the basis of target capture and tracking, the second telemetry device realizes imaging on the tracked target and the background through double-waveband of common optical path design, and records target infrared radiation characteristic data.
