Embodiment Construction

[0023] refer to figure 1. In the preferred exemplary embodiment described below, a kind of aviation station signal source includes: a power supply module connected to the total power supply, a microcomputer control module and a display control interface connected in series through a frequency synthesizer, and it is characterized in that: the power supply module will The input voltage supplies power to each part of the signal source. The microcomputer control module writes the program code according to the communication protocol, and uses the synchronous serial communication method to communicate with the frequency synthesizer through the serial communication interface. The various control signals generated are sent to the frequency synthesizer through the bus. The frequency synthesizer is based on the direct digital frequency synthesizer DDS and the phase-locked loop PLL. According to the relationship between the output frequency of the phase-locked loop PLL, the local oscilla...

Abstract

The aviation radio signal source disclosed by the invention is high in precision, short in conversion time, stable, reliable and high in practicability. According to the technical scheme, a microcomputer control module writes a program code according to a communication protocol and sends instructions of a working mode, a working state and a frequency point code and various generated control signals to a frequency synthesizer through a bus, the frequency synthesizer obtains output frequencies of a first local oscillator and a second local oscillator based on a direct digital synthesizer (DDS) and a phase-locked loop (PLL), and the output frequencies of the first local oscillator and the second local oscillator are transmitted to the frequency synthesizer. The frequency synthesizer generates a corresponding frequency control code to obtain a wave band control code and a corresponding control signal, the signal is processed by the radio frequency signal conditioning circuit and then is output to the to-be-tested equipment, an excitation signal required by the to-be-tested equipment is realized, each frequency value and amplitude required by an aviation radio station are provided, and by setting the hopping speed of frequency hopping, the frequency of the to-be-tested equipment is adjusted. And debugging and testing conventional indexes of the aeronautical radio station for data transmission of the frequency synthesizer, enabling control of frequency conversion and frequency hopping and code word conversion.

Description

technical field [0001] The invention relates to an aviation communication device adopting a frequency hopping communication system, in particular to a portable signal source device of an airborne ultrashort wave anti-jamming aviation radio station. Background technique [0002] With the development of electronic technology, the application of radio communication technology is becoming more and more extensive. More and more avionics equipment adopts the frequency hopping communication system. Frequency hopping communication is also used more and more in modern aviation communication equipment, but the signal Source requirements are also getting higher and higher. In order to ensure the performance of frequency hopping communication equipment, it is necessary to provide a frequency source that is stable, reliable, high-precision, extremely fast in frequency conversion, high in resolution, and capable of digital modulation. The most difficult thing is the realization of frequen...
