Problems solved by technology

[0003] The self-tracking of the existing telemetry receiving antenna is completed by radio frequency. When there are radio frequency signals of similar frequency bands around the aircraft, it will interfere with the telemetry results and cause the target to be lost.

Embodiment Construction

[0011] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0012] see figure 1 , The telemetry target tracking system of the present invention includes a telemetry transmission system, a telemetry ground station, and a telemetry antenna system. The telemetry transmitting system transmits the telemetry signal data packet containing target position information to the telemetry ground station in real time, wherein the target position information is acquired by inertial navigation equipment or GPS equipment. The telemetry ground station receives a telemetry signal packet and processes the packet to obtain target location information. The telemetry antenna system obtains the antenna position information of the telemetry receiving antenna, processes the target position information and the antenna posit...

Abstract

The present invention discloses a remote measurement target tracking method and a remote measurement target tracking system. The method comprises the following steps of S1 using a remote measurement emission antenna to real-timely emit a remote measurement signal data packet containing the target position information to the ground, receiving and processing a remote measurement data packet to obtain the target position information; S2 obtaining the antenna position information of a remote measurement reception antenna; S3 processing the target position information and the antenna position information to calculate an azimuth angle and a pitch angle of a remote measurement target relative to a remote measurement antenna, generating a corresponding antenna servo orientation control instruction and a pitching control instruction to guide the remote measurement reception antenna to align at the remote measurement target. The remote measurement transmission speed is faster, so that the target position information of high frequency and fast update can be provided, and accordingly, the tracking precision of the remote measurement antenna can be improved, and the target can be avoided losing. In addition, the tracking method facilitates keeping the working states of the conventional remote measurement equipment and saves the cost on the condition of not changing the airborne equipment.

Description

[0001] technical field [0002] The present invention relates to the field of aircraft telemetry systems, in particular to a telemetry target tracking method and system for realizing self-tracking of telemetry receiving antennas by using aircraft position information (inertial navigation position information or GPS navigation information), which is applied to the performance of telemetry ground stations during aircraft flight tests. The aircraft telemetry signal is stably received to achieve the purpose of completing the aircraft telemetry signal reception work more effectively. Background technique [0003] The self-tracking of the existing telemetry receiving antenna is completed by radio frequency. When there are radio frequency signals of similar frequency bands around the aircraft, it will interfere with the telemetry results and cause the target to be lost. Contents of the invention [0004] The problem solved by the invention is the problem of target loss in the sel...
