When measuring and tracking the target,pulseradar presence problems that the target can be lost easily in reflex tracking mode and that is difficult to recatch the target when through the black-out.telemetry equipment has a large diameter of the antenna and the narrow beams,so it’s difficult to capture the close and fast targets.optical equipment is difficult to identify and capture the long distance targets.In addition,it’s also susceptible to cloudy weather and lead to tracking instability.In addition,there are no other guide source for the three sets of devices when the central guidance data exception.This article first combined with the actual to carry out theoretical analysis of optical equipment,pulseradar and telemetry equipment to provide guidance each other.At the same time,it also analyzed the favorable conditions for the mutual guidance of the same station equipments.Secondly,based on the problems of the existence of outliers and data delay in synchronous guidance data,we proposed an improved Lagrangian algorithm based on spline fitting and realized the elimination of the outliers in the measurement data and time alignment.Thirdly,aiming at the problem of glitch in the measurement data,we studied a new interest smoothing method based on Kalman filter.The smoothing of the guidance information was realized,and the synchronous guidance data has reached the requirement of real time.Forth,we analyzed the PDXP data communication protocol,and designed the IP network data’send and receive procedures of the same station equipments.Data interworking between equipments was achieved.Fifth,combined with the the actual needs of equipments,we studied the integrated tracking method of the optical,radar,telemetry equipment and completed the design of the synchronous guidance data processing process and software implementation.Sixth,the optical equipment equipment was taken as an example to analyze the synchronous guidance error of radar and telemetry equipment to guide the optical equipment.Finally,we analyzed the reliability of the integrated tracking technology of optical,radar and telemetry equipment with the objective task tracking as an example.Through the research of the integrated tracking technology,the accuracy of synchronous guidance data was improved.Increasing the guidance source,the multisource switching process was without loss,no jump,and the guidance accuracy was high.We achieved the complementary advantages of the optical,radar,telemetry equipment integration.With the advantage of pulse radar’s far tracking distance and high precision tracking accuracy,We improved the optical,telemetry equipment’s capacity to find long-range targets.Using the advantages that optical equipment has a high field of view in the medium wave infrared and it is easy to find and capture the near targets,the radar and telemetry equipment ’s ability of capturing near targets is improved.Telemetry equipment has a strong capability in deep space detection and it’s tracking is stable.These advantages improve the ability of optical devices to identify deep space targets and stable tracking.
