    • The present invention relates to the field of electromagnetic eavesdropping. The invention relates to a method for passively locating a non-movable transmitter (15) on the ground, implemented by a group of at least one receiving station (10), each of the receiving stations (10) comprising a radar detector and a time reference, all the time references being synchronised with one another, said transmitter (15) transmitting a series of periodic pulses, said method being characterised in that a first estimation of the position of said transmitter (15) is carried out by the Bancroft method using the average arrival times of the pulses transmitted by the transmitter (15) at each station (10) of the group of at least one receiving station (10), the obtained result then being used as the starting point of a maximum likelihood method in order to converge towards the position of said transmitter.
    • 电磁窃听领域本发明涉及电磁窃听领域。 本发明涉及一种用于被动地定位地面上的不可移动发射器(15)的方法,所述方法由一组至少一个接收站(10)实现,每个接收站(10)包括雷达检测器和时间 其中所有时间参考彼此同步,所述发射机(15)发射一系列周期性脉冲,所述方法的特征在于,所述发射机(15)的位置的第一估计通过Bancroft方法使用 在至少一个接收站(10)的组的每个站(10)处由发射机(15)发射的脉冲的平均到达时间,然后将获得的结果按顺序用作最大似然法的起点 朝向所述发射机的位置会聚。
