时差定位卫星簇的时域关联干扰方法研究

Analysis of the jamming method based on time domain correlation against the satellite cluster of TDOA location

时差定位卫星簇对地表的辐射源存在很大威胁。为保护目标辐射源,在分析时差定位卫星簇TDOA脉冲配对的原理的基础上,提出一种新的主动干扰方法。即通过控制干扰脉冲与辐射源脉冲之间的时域关联关系,达到欺骗时差定位卫星的TDOA估计。仿真计算表明,适当的脉冲发射时间和脉冲宽度的同频干扰源对辐射源位置信息的保护具有可行性和有效性。

Satellite cluster based on TDOA location technology is usually to achieve target detection and geolocation. It＇s a big threat to all the emitters on the earthrs surface. To protect emitters from being located by the satellite cluster, a new active jamming method is proposed to deceive the satellite cluster after analyzing the principle of pulse pairing histogram used in TDOA location. By controlling the relationship between jamming pulse and emitter＇s pulse in domain of time, the jamming pulse can disturb the satellite cluster to estimate the emitterrs TDOA. After simulation, it demonstrates that it is effective in covering the emitter＇s position by choosing the jamming pulses of appropriate time of transmitting and width.
