A method for measuring certain parameters of the impulse response of a propagation channel involving emitters and reflectors that are fixed or mobile, so as to detect and determine the parameters regarding the position and kinematics of these emitters and reflectors, or to auto-locate the reception system implementing the invention, in a system comprising N sensors receiving signals from said emitters or from the reflection on said reflectors, and comprising at least the following steps: determination of an ambiguity function which couples the spatial analysis and the delay-distance/Doppler-kinematic analysis, determination of at least one sufficient statistic C(, m, K) corresponding to the correlation between the known signal s(kTe) corresponding to the complex envelope of the signal emitted and the output of a filter w(,m) where 1 corresponds to a temporal assumption (delay-distance, temporal ramp, etc.) and m to a frequency assumption (Doppler-kinematic, Doppler ramp, etc.), determine the values of the pair (, m) by comparing the value of the statistic for the pair (, m) with a threshold value. |
