Abstract

The invention discloses a navigation signal power enhancement method for low-earth-orbit satellites based on Ka-band multi-beam antennas. The Ka-band multi-beam antenna is a phased array transmittingantenna including multiple array element antennas and capable of simultaneously transmitting communication signals and navigation signals. According to the navigation signal power enhancement method,all beams formed by multiple low-earth-orbit satellite multi-beam antennas are enabled to point to a navigation signal power enhancement target area, and the signal landing power is improved. In addition, antenna pointing control is carried out based on satellite orbit change information so as to enable the antenna beams to continuously point to the navigation signal power enhancement target area.According to the method, the low-earth-orbit satellites can provide continuous navigation signal power enhancement services for the target area with less power consumption, and the low-earth-orbit satellites are integrated with the low-earth-orbit communication satellites to improve the functional density of the communication satellites.

Description

technical field [0001] The invention relates to the technical field of satellite navigation signal anti-jamming, in particular to a low-orbit satellite multi-beam antenna and a Ka frequency band navigation signal power enhancement method using the antenna. Background technique [0002] Due to the high orbit of the Global Navigation Satellite System (GNSS) satellites, they are far away from the users, and the level of reaching the users is low, so the navigation signals are easily interfered or shielded and the service is interrupted. On the other hand, due to the wide coverage of satellite signals, the basic goal is to provide wide-area services, and the satellite itself is in constant motion, so it lacks the ability to adapt to complex terrain and continuous coverage, which makes it difficult to Signal received. Especially when GNSS is applied in the theater, due to the complex geographical terrain and harsh electromagnetic environment in the combat area, the above problem...
