Description
Technical Field
The invention belongs to the technical field of measurement, control and application of spacecrafts, and relates to a scanning capture method based on a paraboloid unified measurement and control antenna.
Background
The acquisition mode of the antenna system for the spacecraft is determined by the antenna type. At present, a scanning and capturing mode is widely applied to radar antennas and phased array antennas, and tracking objects of the antennas are usually non-cooperative targets and are characterized in that target motion tracks are uncertain. The radar antenna mainly adopts a rapid mechanical scanning mode to capture a target, and the phased array antenna mainly adopts an electric beam synthesis mode to realize scanning capture.
Although phased array antennas have also been introduced in the field of spacecraft measurement and control to adapt to multi-target measurement and control, the main problem to be solved is that multi-beam corresponds to multi-target or beam synthesis to improve antenna gain, rather than scanning and capturing. At present, a ground measurement and control system widely adopts a large-caliber paraboloid measurement and control antenna, as a tracked object is a cooperative target, a main capture mode is to calculate a guide angle according to the number of tracks or track data, then wait for the target to enter a beam range at a waiting point according to the guide angle (called waiting point capture), or control the antenna to continuously move to approach the target to complete capture in a time-coincidence mode (called guide capture), and the two modes are characterized by being very dependent on the number of tracks or the accuracy of a theoretical track.
Due to the limitation of the use mode, the large-scale paraboloid unified measurement and control antenna does not consider the scanning and capturing requirements during design and development, and does not have the function of capturing the target according to the track scanning. Under the conditions that the spacecraft has large dynamic and is greatly influenced by the space environment, no radar is available on the running track to track the spacecraft so as to provide guiding data, the theoretical orbit or the actual orbit of the spacecraft has large uncertainty, and if the parabolic antenna still adopts the traditional waiting point capturing and guiding capturing mode, a target can not enter a beam range to complete capturing and tracking.

As shown in fig. 2, the antenna gain at the center point of the antenna beam width is the largest and the convergence characteristic is the best, and the target is easily captured by the antenna at this position; if the range of the antenna beam is exceeded, the antenna gain is sharply reduced, the antenna convergence characteristic is reduced, and the target cannot be captured by the antenna when the target is located at the edge of the antenna beam.
