1. signal source positioner, comprise a plurality of receivers with diverse location, this signal source positioner comprises the delay difference that postpones between the input signal that the difference estimation unit is used to estimate that at least two receivers receive, and position determining means is used for determining the position of signal source according to postponing difference, this signal source positioner is characterised in that, the signal source positioner comprises that impulse response determines device, be used for determining the function of the impulse response in path between a plurality of expression signal sources and the receiver, described impulse response determines that device comprises:

  • Tunable filter is used for obtaining filtered signal from the input signal that receiver provides;

    Composite set is used for obtaining composite signal from filtered signal;

    WithControl device is used to control tunable filter so that maximize the performance number of composite signal, and said control device is used to the combined power yield value of filtered signal is restricted to predetermined value;

    Wherein postponing the difference estimation unit is used for determining to postpone difference according to described function.
