FIELD: radiolocation, sound fixing and ranging, space scanning and determination of spatial coordinates of distant objects. SUBSTANCE: proposed space scanning method consists in radiation of probing signal into some region of space with the use of transmitting antenna and in receipt of echo signals in set of N spatial channels by means of receiving antenna. Pulse signal with low relative pulse duration is used as probing signal. During transmission and reception uninterrupted scanning of radiation patterns of transmitting and receiving antennas is carried out by such laws specified beforehand that directions of maximums of radiation patterns do not coincide in space at unspecified time moment. Moments tof maximums of echo signals are registered in each nth (n=1,...,N) spatial reception channel. After this there are determined range and angular coordinates of object depending on specified laws of scanning which maximum echo signal is registered in nth spatial reception channel at time moment t.. EFFECT: increased range with preservation of high rate of space scanning. 1 cl, 7 dwg |
