| Abstract: | 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. |
