METHOD FOR DETECTING OBJECTS IN ACTIVE LOCATION Russian patent published in 2018 - IPC G01S3/74 

FIELD: measuring equipment.

SUBSTANCE: invention relates to an active location, namely to methods for processing echoes using superresolution tools for use in information and measurement systems based on the processing of signals reflected from the object of detection, that is, acoustic location and sonar detection, operating in modes of active recognition of low-contrast targets. Technical result is achieved by the fact that the method is realized by the steps of receiving echoes by separate elements of the antenna array, by preliminary amplifying them, by filtering and digitizing them, after which the digital signals are filtered by filters matched to the shape of the sounding signals and transmitted to the processing units that provide superresolution for key characteristics of echoes and objects such as frequency, range, velocity and bearing.

EFFECT: technical result of the proposed invention is an increase in noise immunity.
