FIELD: radiolocation. ^ SUBSTANCE: the radar unit has a transmitter, circulator, polarimeter, antenna, two-circuit receiver, signal adding and subtraction circuit, whose outputs are detected and subjected to subtraction by another subtraction circuit. The result of subtraction is processed by a multideflecting delay line with N deflections distant in delay for the period of radar repetition by N full-wave rectifiers, unit for estimation of the parameter of the spread of static distributions of signals of the target and interference. As a result of processing the estimations of the parameters of the spread in the adjacent intervals of resolutions in the range of the sounding signals are computer, and according to their relation the presence of the target signal is judged. ^ EFFECT: enhanced efficiency of operation of the radar due to the reduced loss of the target signals against the background of interference of landmarks by taking into account the numerical characteristics of static distributions of radar output signals, in particular, the parameters of the spread between the interference signals and target signals. ^ 2 cl, 2 dwg |
