Embodiment 1

[0053] The ultra-wideband digital satellite beacon receiver based on software defined radio includes: ultra-wideband radio frequency front-end chip AD9361 based on software defined radio, digital signal processing module chip ZYNQ7010 and a power supply module.

[0054] The ultra-wideband RF front-end chip AD9361 amplifies the input intermediate frequency signal according to the frequency control and power control information fed back by the digital signal processing module chip ZYNQ7010, and down-converts the frequency to 0-30MHz zero intermediate frequency I and Q signals through the quadrature mixer , output to the low-pass filter, and perform high-speed AD processing, so that the back-end digital signal processing module chip can work. The digital signal processing module chip adopts the chip ZYNQ7010 of XILINX Company, and the ZYNQ7010 chip has built-in frequency calculation module, power calculation module and control interface module. The clock frequency of ZYNQ7010 is ...

Abstract

The invention discloses a software radio-based ultra-wideband digital satellite beacon receiving method and a receiver. The receiver comprises an ultra-wideband radio frequency front end and a digitalsignal processing module, whose signals are mutually communicated, and a power supply module for providing power for the ultra-wideband radio frequency front end and the digital signal processing module, wherein the ultra-wideband radio frequency front end includes a variable gain amplifier, a quadrature mixer, a local oscillator, an I-channel amplifier, an I-channel filter, an I-channel ADC, anda Q-channel amplifier, a Q-channel filter and a Q-channel ADC; the digital signal processing module includes a frequency calculation module, a power calculation module, and a control interface module. According to the method and the receiver, a digital signal processing method, and self-adaptive frequency adjustment and gain adjustment are used for carrying out precise frequency and power calculation on a satellite beacon signal, and outputting frequency and power information to an antenna controller to form an antenna turntable driving command to complete the alignment satellite process. Themethod and the receiver have the advanteges of ultra-wideband operation, large dynamic range, high integration, stable and reliable performance, strong universality and the like.

Description

technical field [0001] The invention relates to an ultra-wideband digital satellite beacon receiver, in particular to an ultra-wideband digital satellite beacon receiving method based on software radio technology and a receiver, belonging to the technical field of satellite communication. Background technique [0002] With the continuous development of satellite technology, satellite communication is widely used in military, news, firefighting, emergency rescue, business and other fields due to its high reliability, good confidentiality, and fast transmission speed. Manufacturers who design and produce satellite receiving terminals and equipment It has grown rapidly like mushrooms after a spring rain, making the price of satellite communication receiving terminals and equipment continue to decrease, and is developing in the direction of generalization and miniaturization. [0003] The satellite beacon signal is a special signal emitted by the satellite to represent the exi...
