Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] Only using space-based angle measurement to realize rapid and accurate detection of orbital maneuvers of space objects depends on the solution of the following problems, namely, the selection of detection quantities, hypothesis testing methods, detector structure and determination of corresponding parameters, etc.

[0020] Step 1. Quantity selection

[0021] The selection of the detection amount needs to fully consider the speed and degree of its response to the change of the motion state, so as to directly determine the accuracy of the orbital maneuver detection of the space object. In the process of motion state estimation of space objects, measurement innovation, as an important parameter of state estimation method, can accurately reflect the accuracy of state estimation and fully reflect the real-time changes of motion state. Therefore, in the curr...

Abstract

The invention discloses a space target track maneuvering fusion detection method for only space-based angle measurement tracking. The space target track maneuvering fusion detection method comprises a detection quantity selection method and a hypothesis test method. The detection quantity selection method takes measurement information in state estimation as detection quantity. The hypothesis test method performs hypothesis test by use of five test methods, namely, an X<2> test method, a skewness-kurtosis test method, a Jarque-Bera method, a Kolmogorov-Smirnov method, and a Lilliefors method. The space target track maneuvering fusion detection method further comprises a weighted fusion detection method. Linear weighted fusion is performed on the detection results of the five test methods to get a linear weighted detection fusion result. When the detection fusion result is greater than or equal to a maneuvering detection judgment threshold V-horizontal line, it can be judged that orbital maneuver occurs to a space target. According to the invention, the advantages of a variety of hypothesis test methods are fully utilized, the success rate of space target track maneuvering detection is improved, the detection result of a short detection window is improved, the demand for the length of a detection window is reduced, and the redundancy and robustness of the system are improved.

Description

technical field [0001] The invention belongs to the technical field of space target tracking, and in particular relates to a space target orbit maneuver fusion detection method which only uses space-based angle measurement to track. Background technique [0002] Space situational awareness technology uses the measurement information of space targets to determine their status, attributes and intentions. It is the main response and prevention means for space security issues at present. One of its important contents is the real-time and accurate estimation of the motion state of space objects and the change of motion state. fast and accurate detection. From the perspective of information acquisition means of space targets, space-based observations have been highly valued and widely used in recent years because they are not restricted by ground illumination, meteorological and geographical conditions, such as the US Space-Based Space Surveillance System (SBSS) and orbital deep s...
