Abstract

The invention provides a shielding device for aircraft anti-jamming satellite receiver testing, the shielding device includes a casing, a radome, a wave-absorbing layer, a transmitting antenna group and a monitoring receiving antenna, the casing, the radome and the aircraft casing Together form a closed cavity, the wave-absorbing layer is set on the inner surface of the shell, the wave-absorbing layer is used to absorb the reflected radio waves inside the shell, the transmitting antenna group is set on the radome, and the transmitting antenna group is used to send anti-jamming satellite receivers The test signal is transmitted, the monitoring receiving antenna is arranged on the radome and arranged in parallel with the receiving antenna of the anti-jamming satellite receiver, and the monitoring receiving antenna is used to receive the test signal transmitted by the transmitting antenna group and output the received test signal to the outside for use External real-time monitoring. The technical solution of the present invention is applied to solve the technical problems that the receiver test method in the prior art cannot establish a relatively clean wireless test environment for the anti-jamming receiver, occupies a large area, and has high construction and maintenance costs.

Description

technical field [0001] The invention relates to the technical field of satellite navigation receiver testing, in particular to a shielding device for aircraft anti-jamming satellite receiver testing. Background technique [0002] The anti-jamming satellite receiver test usually needs professional equipment such as wireless shielding chamber and satellite navigation signal simulation source as the test environment support. In the whole test environment, a radio wave shielding chamber is required to simulate the radio wave open field, and the radio wave shielding chamber has a large area. , high cost and maintenance costs. [0003] During the ground test of the product, the anti-jamming satellite receiver needs to be tested and detected. In order to effectively shield other signals, it is necessary to establish a relatively clean wireless test environment for the anti-jamming satellite receiver during the test process. The currently commonly used indoor open test method will ...
