FIELD: physics.
SUBSTANCE: method involves breaking a controlled area in space into position resolution elements; determining amplification coefficients generated by a receiving antenna for each resolution element for selected directions of the axis of the beam pattern of the antenna; forming n amplification matrix
where Wi(ej) is the power amplification coefficient generated by the antenna when receiving radiation from the i-th resolution element for the direction of the axis of the beam pattern ej; measuring power at the antenna output for selected directions of the axis of the beam pattern; estimating the signal vector based on an equation of measurements p=Wf+n, where p is the power measurement vector, n is the power measurement error vector at the output of the receiving antenna, f is the source power vector, the component number of which is equal to the number of the resolution elements, where the i-th component is equal to zero, if there is no radiation source in the i-th resolution element, and is equal to radiation source power if there is a radiation source in the i-th element; determining the position and power of radiation sources based on the source power vector estimate.
EFFECT: wider range of using the method of determining the position of sources on passive single-position local systems, easier measurement and high information content owing to determination of the power of the sources.
