Experiment teaching system of electronic countermeasures technology

Abstract

The invention relates to an experiment teaching system of an electronic countermeasures technology, wherein the method is applied to the technical field of the electronic countermeasures of the electronic information major of the institution of higher learning. The system comprises a hardware part and a software part. A directional receiving antenna is used for receiving a signal; the signal is sent to a low-noise small-signal resonant amplifier by a duplexer for amplification; a power divider divides the signal into four paths of signals that are sent into analog mixers; and down conversion is carried out to obtain analog intermediate-frequency signals. Each paths of mixing input with a difference of 30MHz is provided directly by a digital frequency synthesizer, so that a 120-MHz bandwidth signal can be received simultaneously. After obtaining a digital signal based on analog-to-digital conversion, the signal is sent into a signal analysis processor to carry out analysis processing, thereby obtaining a signal feature parameter. According to the system, the hardware circuit employs the double frequency mixing circuit to carry out investigation and giving interference on double channel signals; reliability of the digital experiment system is high; and the post operation and maintenance costs are reduced.

Description

technical field [0001] The present invention relates to an electronic countermeasure technology experimental teaching system in the field of electronic countermeasure technology of electronic information majors in colleges and universities, more specifically, an electronic countermeasure principle and method teaching experimental system applied to electronic information majors in colleges and universities , It is mainly used to train students majoring in electronic information in colleges and universities to learn, apply, design and develop the electronic countermeasure system. Background technique [0002] At present, electronic countermeasures refer to various electronic measures and actions taken by hostile parties to weaken and destroy the effectiveness of the opponent's electronic equipment and ensure the effectiveness of their own electronic equipment, also known as electronic warfare. Electronic countermeasures are divided into three aspects: electronic countermeasure...
