Abstract:

When the measurement and control equipment tracks and measures the flying target, it is difficult to capture the flight target with the high tracking accuracy equipment. Generally, by the guidance of device with low tracking accuracy, the antenna approaches to the target and then turns into self tracking mode. Therefore, the mutual guidance of the station measurement equipment is an important mean for target acquisition. Directing at the technical requirements that high precision measurement equipment was guided by the low precision measurement equipment, this paper proposed an algorithm for real-time correction of low-precision equipment tracking data by using high-precision equipment tracking information when two sets of monitoring and control equipment shared the same target. The algorithm realized real-time estimation and extrapolation of trace residual and improved the accuracy of same station guidance. Finally, the experiment the photo-electric theodolite guided by the telemetry equipment. It is verified that the processed telemetry data can guide the photo-electric theodolite to capture the target. Finally, telemetering equipment was used to guide the photoelectric theodolite to carry out experiments. The verification showed that with use of the corrected telemetry equipment tracking data,the photoelectric theodolite could effectively capture the targets.
