Problems solved by technology
During the satellite launch phase, when the ground radar equipment uses a fixed power to transmit signals, due to the large-scale changes in the distance between the satellite and the ground radar equipment, the spatial attenuation of the signal changes greatly, that is, the distance will cause power loss
The greater the distance between the satellite and ground-based radar equipment, the more significant the power loss, which may cause the satellite transponder to receive signals outside its dynamic range
When the signal is too small, it will be lower than the sensitivity. When the signal is too large, it will cause saturation. If the signal is too small or too large, it may reduce the accuracy of orbit measurement data, and even cause the tracking loss of radar equipment, and cannot provide data transmission support for satellites.

Embodiment Construction
[0079] In order to be able to understand the above objects, features and advantages of the present invention more clearly, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments may be combined with each other in the case of no conflict.
[0080] The present invention will be described in detail below with reference to the accompanying drawings. According to the method for adjusting the uplink power of radar equipment according to the embodiment of the present invention, the dynamic range δ of the satellite transponder is preset, and the dynamic range of the satellite transponder is the maximum signal power P that can be received by the satellite transponder. max with the minimum signal power P min The ratio is taken as the logarithm of base 10, that is
[0081] The corresponding automatic gain...

The invention relates to a method for adjusting uplink power of radar equipment, which comprises the following steps of: binding a network card and a port number of a centralized processing terminal into an uplink power adjusting system of the centralized processing terminal in the uplink power adjusting system of the integrated processing terminal to complete network parameter initialization, and setting a buffer area for receiving data in the centralized processing terminal, and setting, querying and processing the power of the power amplifier to ensure that each ground radar device Ai in the transit arc section of the satellite is online. Coherent demodulation is carried out on a downlink signal of a satellite responder through baseband equipment of a ground radar system, a downlink measurement frame is obtained, and whether a display result of an uplink power adjustment system needs to be changed or not is determined. In the tracking process, it should be preferentially guaranteed that the power of the measurement master station meets the tracking requirement; the manual adjustment mode needs to be carried out one by one according to the automatic gain control voltage and the dynamic range of a target responder communicating with the automatic gain control voltage.
Description
technical field [0001] The present invention relates to the technical field of tracking measurement, and more particularly, to a method for adjusting the uplink power of radar equipment. Background technique [0002] Radar equipment provides data transmission support for the launch and operation of rockets and satellites. In the satellite launch stage, when the ground radar equipment uses fixed power to transmit signals, due to the large-scale change in the distance between the satellite and the ground radar equipment, the spatial attenuation of the signal changes greatly, that is, the distance will cause power loss. . The greater the distance between the satellite and the ground-based radar equipment, the more significant the power loss, which can cause the satellite transponder to receive signals beyond its dynamic range. When the signal is too small, the sensitivity will be lower than that when the signal is too large, and saturation will occur when the signal is too la...
