Embodiment

[0055] Embodiment: Taking a specific telemetry device as an example to illustrate the realization of the telemetry antenna autonomous tracking module.

[0056] At present, the new generation of telemetry equipment ACU (antenna control unit) adopts a set of common ACU software products. The product encapsulates complete control over the basic control requirements of an A / E mount (or similar 2-axis / 3-axis mount) servo, and uses dynamic module loading, allowing the product to be The support for the external equipment of the measurement and control system is realized by means of hardware, thus forming a complex servo system antenna control application. In this embodiment, an autonomous tracking module is designed and written on a specific telemetry device.

[0057] This module mainly provides the implementation function of tracking strategy, including:

[0058] (1) Selection of waiting point;

[0059] (2) Entry criterion processing of tracking methods such as program guidance, ...

Abstract

The invention discloses a telemetering antenna automatic tracking control method, and belongs to the technical field of telemetering antennas. After a task trajectory file is received from a center, atrajectory is loaded into a module in advance, and an antenna is rotated to a waiting point; when a flying target passes by the waiting point of the antenna, under a program guiding working mode or adigital guiding working mode, the antenna is driven to rotate to a position with a pitching angle larger than 2 degrees, a receiver is locked, and an automatic tracking working mode is switched on; when the signal of the flying target is lost halfway, a target flying track is extrapolated for 5 s, when the target signal is lost and the receiver is unlocked, the antenna is switched to a memory mode firstly, and once the tracking conditions are satisfied, the antenna is immediately switched to the automatic tracking mode; a target tracking elevation angle of the antenna is smaller than a presetvalue, the value of Rbyte is not equal to 1 or 2, and when the departure time is longer than 30 seconds, the antenna is immediately switched to an orientation working mode. The telemetering antenna automatic tracking control method improves the timeliness, accuracy, tracking stability and reliability of capture of a telemetering device, and improves the capability of completing an experimental task.

Description

technical field [0001] The invention belongs to the technical field of telemetry antennas, and in particular relates to an autonomous tracking control method for telemetry antennas. Background technique [0002] The antenna tracking flight target is to receive the error signal from the receiver through the servo system, digitally process and amplify it, and finally feed it back to the actuator servo motor to drive the antenna to the direction to reduce the error, so as to complete the capture and tracking of the flight target. Automatic tracking is a closed-loop control system that can track the target without human intervention, but once the signal of the target is abnormal (or weakens or disappears for a short time), the closed-loop system will collapse and the tracking will fail. [0003] The autonomous tracking of the antenna puts more emphasis on the handling of abnormal signals by the antenna control system, and the tracking method can be automatically selected accordi...
