ACTIVE RADAR METHOD Russian patent published in 2013 - IPC G01S13/00 

FIELD: radio engineering, communication.

SUBSTANCE: method involves radiating multi-frequency probing signals from r_i(i=1, …, N) points of a transmitting antenna, receiving reflected signals regardless of detection of partial radio holograms in points at frequencies of the received signals and combining them into a resultant radio hologram while placing the partial radio holograms in the ordered coordinate space of the location of each transmitting-receiving point and carrier frequencies taking into account Doppler frequency. To restore a set of hypotheses is created, which includes a combination of desirable and accompanying parameters on the partial radio hologram accumulation interval, taking into account possible trajectories of transmitters, receivers and objects located in the probed space; a model of the probing process is used to calculate the reference resultant radio hologram for each hypothesis; the resultant radio hologram is compared with all reference radio holograms and values of all unknown parameters are determined while determining values of the desirable parameters. Use of the method in radar systems of different types and purposes increases information value and simplifies the radio part of systems implementing the disclosed method.

EFFECT: wider field of use owing to high information value of the method.
