Embodiment Construction

[0033] see figure 1, a Beidou receiver anti-interference automatic test system, mainly composed of a host computer, a satellite signal and interference signal simulation source, a receiver under test and a rotating platform. The satellite signal and interference signal simulation sources include DSP information processing module, FPGA signal processing module, multi-channel DA conversion module, multi-channel radio frequency module and multiple transmitting antennas. The upper computer is connected to the DSP information processing module, and the DSP information processing module and the FPGA signal processing module are connected to each other. The output of the FPGA signal processing module is divided into multiple channels, and each channel is connected to a radio frequency module through a DA conversion module. Each radio frequency module There is a transmitting antenna connected to them. The above-mentioned multiple transmitting antennas are arranged around the rotating...

Abstract

The invention provides a method and a system for automatically testing the anti-interference performance of a Beidou receiver. The method comprises the following steps: a satellite signal and interference signal simulation source receives setting parameters transmitted by an upper computer, simulates a motion track and state of a user and generates a Beidou satellite navigation signal and various interference intermediate frequency digital signals; the generated Beidou satellite signal and multiple interference signals are transmitted from different positions and directions through antennas through digital / analog (AD), up-conversion and power regulation; a tested receiver is arranged on a rotating platform and rotates along the rotating platform; and the receiver simultaneously receives the satellite signal and multiple interference signals, finishes anti-interference processing, signal processing and navigation calculation of the signals, outputs corresponding positioning results in different interference modes and outputs the results to the upper computer, and the upper computer finishes the anti-interference performance evaluation of the receiver and outputs the evaluation result. The anti-interference capacity of the receiver in the time domain and the frequency domain can be tested, and the anti-interference capacity of the receiver in the space domain can be tested.

Description

technical field [0001] The invention relates to the field of satellite navigation, in particular to a method and system for automatically testing the anti-jamming performance of a Beidou receiver. Background technique [0002] Satellite navigation has penetrated into all aspects of modern warfare and has become a powerful means to gain military advantage and even win combat. It plays an irreplaceable role in every link of the war process. Interfering with satellite navigation can not only destroy stealth aircraft, cruise missiles and Accurate attacks by other combat aircraft can also destroy the operational coordination between them, which can play an important role in the victory of anti-air strike operations. As a constantly improving and powerful navigation and positioning system, Beidou (BD) will exert great power in the information war under high-tech conditions, but at the same time it will continue to expose its own weaknesses and face various challenges. Only by und...
