Method for estimating transmission power of deception jamming signal

Abstract

The invention provides a method for estimating the transmission power of a deception jamming signal. The method comprises the steps that: a radar beam points at a real target, a radar transmitter transmits a radar signal, a reconnaissance plane intercepts the radar signal, and the transmission power of transmitting the radar signal by the radar transmitter is estimated; a false target for realizing a deception jamming effect is realized, and the echo power of a real target at the position of the false target received by a radar receiver is estimated; the jamming signal power received by the radar receiver when effective jamming is generated is estimated; and according to the power range of the jamming signal received by the radar receiver, the transmission power of the jamming signal is estimated. According to the method, through considering the attenuation of signal space propagation by environmental factors and reflecting the attenuation to a propagation factor in the estimation process of the signal transmission power, the jammer transmission signal power for deception jamming under an effective jamming condition can be more accurately obtained.

Description

technical field [0001] The invention belongs to the technical field of signal processing, in particular to a method for accurately estimating the transmitting power of a signal used for deceiving interference in electronic countermeasure applications. Background technique [0002] In the process of electronic countermeasures, using jammers to interfere with the opponent's tracking and guidance radars, reducing the combat effectiveness of the opponent's radar-guided weapons, and capturing and maintaining local information advantages has become the key to the current confrontational parties seizing the initiative. Deceptive radar jamming is one of the important means of electronic attack on the opponent's radar. Whether the electronic deception jamming can be effectively implemented has an important impact on one's own initiative and support operations in information countermeasures. Today, the identification of active spoofing jamming can only be judged by the magnitude of th...

Problems solved by technology

[0003] There is no qualitative calculation formula for the power estimation of traditional deceptive jamming signals, but it mainly considers the free space conditions and roughly estimates the jamming power emitted by the jammer according to the false target information set by one's own side; and the estimation process does not consider the ground The impact of (sea surface) and its propagation medium on the propagation of radar signals in space will cause large errors in the calculation of interference power, and it may even be possible that the interference power calculated under this condition cannot achieve the expected deception effect, thus affecting existing Combat Situation
