Title Research on deception jamming of Radar Seeker
Abstract The radar seeker is the measuring equipment installed on the missile, which is the key component of the electromagnetic wave guided weapon。 As an important function of radar seeker's target orientation and precision guidance, the angle measurement becomes one of the most basic and important functions of radar seeker。 With the continuous development of science and technology, electronic warfare has become a national war, defense, reconnaissance, electronic warfare, such as a major change in the type of war。
The research direction of radar guided seeker angle deception jamming, first of all according to the principle of monopulse, using MATLAB simulation and analysis, and add interference in angle measurement based, non respectively coherent interference and non coherent interference and cross polarization interference and towed decoy, and simple derivation of the formula。 According to the interference method, after Matlab simulation, the relationship between the corresponding parameters and the error angle is concluded according to the simulation graph。 Finally, some interference methods are compared, and the advantages and disadvantages of the corresponding interference are concluded。
Keywords: Radar seeker Coherent interference non coherent interference Cross polarization interference Towed jamming interference
