METHOD FOR ENSURING HIGH RESOLUTION OF A RADIO LOCATION APPARATUS IN RANGE BY SELECTING THE OPTIMAL INVERSE FILTER REGULARISATION PARAMETER Russian patent published in 2021 - IPC G01S7/292 G01S7/36 G01S13/52 

FIELD: radio location.

SUBSTANCE: invention relates to the theory of super-Rayleigh resolution of signal recovery and is intended for interference-resistant radio location systems for various purposes, in particular, for resolution of individual objects reflecting an emitted signal by a radio location apparatus in range, wherein said objects are located in half of the pulse volume formed by the parameters of the emitted signal. To realise the described result, a method for analysing the smoothed pulse characteristics of the medium of reflection of the signal emitted by the radio location apparatus is applied in the claimed method for resolution of the probing signal reflection sources of a radio location apparatus in range. According to this approach, to make a decision on the number of reflections of the probing signal, the most plausible amplitude value is selected from the smoothed pulse characteristic of the medium of reflection of the signal emitted by the radio location apparatus and mutual location thereof relative to each other, for the purpose whereof the least-squares method is used, and the obtained result is subjected to threshold processing.

EFFECT: providing a high resolution of the radio location apparatus in range, wherein the resolution does not require a priori known information on the amount of reflections of the probing signal and mutual distance thereof from each other.
