Abstract

The invention is applicable to the technical field of computers, and particularly relates to a radio frequency shielding method and device, and computer equipment. The radio frequency shielding methodspecifically comprises the steps of acquiring a target radar echo signal received by a first receiving channel and an external interference signal received by a second receiving channel; carrying outdigital processing on the external interference signal, and carrying out characteristic analysis on the digitalized external interference signal to obtain attribute function characteristic information of the external interference signal; determining an interference analysis result according to the attribute function characteristic information of the external interference signal and attribute function characteristic information of the target radar echo signal; and adjusting a radio frequency shielding emission frequency and a time sequence of radar emitted signals according to the interferenceanalysis result, and carrying out radio frequency shielding emission. According to the method, the external interference signal is acquired in real time and is subjected to cognitive analysis, and ananti-interference strategy is adjusted, so that intelligent interference resistance of a radar radio frequency shielding system is realized.

Description

Technical field [0001] The present invention relates to the field of computer technology, in particular to a radio frequency shielding method, device and computer equipment. Background technique [0002] Radio frequency shielding is a kind of tactical and technical behavior that actively and intentionally radiates electromagnetic signals to deceive or disrupt the enemy's electromagnetic detection and reconnaissance equipment, consumes the enemy's combat resources, and protects its equipment, personnel, and electromagnetic information. [0003] A radar with radio frequency shielding function usually transmits a radio frequency shielding signal of other frequencies before the working signal to deceive the jammer. If the jammer receives the radio frequency shielding signal and thinks it is a radar working signal, it will cover the radio frequency The signal interferes; while the radar does not process the radio frequency shielding signal, but only processes the working signal, it has ...
