FIELD: physics.
SUBSTANCE: method involves performing azimuth resolution by expansion of probing signal spectre due to inter-stroke binary phase manipulation of probing pulse according to codes described by periodic linear recurrent digit sequence, coordinating the manipulation period with beam pattern width in azimuth plane, and multichannel echo signal accumulation synchronised with the probing signal manipulation. Multichannel echo signal accumulation is separated into partial coherent accumulation of azimuth train with compensation in Doppler phase progress channels for single impulses from moving target, and further post-detection accumulation of the whole train. Azimuth resolution method is implemented in the claimed method of surveillance pulse RLS operation and in radar system.
EFFECT: improved azimuth resolving power within antenna beam pattern (BP).
