METHOD OF SPACE RADAR SCANNING Russian patent published in 2018 - IPC G01S13/00 

FIELD: radar ranging and radio navigation.

SUBSTANCE: invention relate to the field of radar ranging and can be used in the radar location systems (RLS) consisting of radar location modules (RLM): radar ranging stations or transceiver modules. Space radar scanning method by the system of n≥2 radar location modules RLM₁…RLM_n with wavelengths of λ₁>…>λ_n is based on the coordinates successive updating, at that the space scanning and the targets containing sector angular coordinates determination are carried out by the RLM₁ with the longest wavelength, after which, with n>2, updating the moving targets angular coordinates with the help of RLM with smaller wavelengths, and with the help of RLM_n with the smallest wavelength in the sector with updated angular coordinates, detecting moving targets and measuring their coordinates; during the angular coordinates updating, using the signals with ambiguous range, ensuring the targets resolution by speed; and with n=2 during the space scanning with the help of the RLM₁ with the longer wavelength λ₁ using the signals with ambiguity in range, resolving the targets by speed, with the help of RLM_n with the shorter wavelength, detecting the targets in sector, in which, with the help of RLM₁ moving targets are detected, and measuring their coordinates.

EFFECT: suppression of passive interference acting in the individual RLMs wavelength range.
