Estimate method of transmitting power for suppressing interference signal

Abstract

The invention relates to a blanketing jamming signal transmission power estimation method. The method comprises the following steps that: a radar beam points to a target, a radar transmitter transmits radar signals, a reconnaissance plane intercepts the radar signals and estimates the transmitting power of the radar signals; a radar receiver receives target echoes and estimates the power of the target echoes; the power of interference signals received by the radar receiver under a condition that desired interference is generated is estimated; and the transmission power of interference signals transmitted by a jammer is estimated according to the power of the interference signals received by the radar receiver. According to the blanketing jamming signal transmission power estimation method of the invention, the attenuation of signal space propagation caused by environmental factors are considered; the attenuation is embodied on a propagation factor in the estimation process of the transmission power of the signals; and therefore, the signal transmission power of the jammer for blanketing jamming under an effective interference condition can be obtained more accurately.

Description

technical field [0001] The invention belongs to the technical field of signal processing, in particular to an accurate estimation method for signal transmission power used for suppressing 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. Active suppressive jamming is one of the simplest and most commonly used jamming methods in the process of electronic countermeasures. Whether active suppressive jamming can be implemented has an important impact on the initiative of one's own countermeasures and support operations in information countermeasures. Nowadays, most of the identification of radar active suppressi...

However, this process does not consider the influence of the ground (sea surface) and its propagation medium on the propagation of radar waves in space, which will cause large errors in the calculation of interference power, and may even fail to achieve the expected interference power under this condition. Suppressive effect, thereby affecting one's own combat situation

Moreover, radars seldom work under the conditions of approximate free space, and the vast majority of practical radars will be affected by the ground (sea surface) and its propagation medium. Therefore, the path loss of signal propagation must be considered in the accurate estimation of interference power practical problems
