METHOD OF COMBINED RADAR AUTOMATIC DETECTION AND ROUTE TRACKING, CIRCULAR OBSERVATION OF AIR, ON GROUND, OVER-WATER TARGETS, LOCAL RADIO COMMUNICATION AND NEAR RADIO NAVIGATION OF OBJECTS AND SUBJECTS Russian patent published in 2007 - IPC G01S13/42 G01S13/72 

FIELD: radiolocation.

SUBSTANCE: radio pulse sequence is irradiated from several apart-standing positions of specific duration to have specified period of repetition. Groups of radio pulses are received or radiated alternatively during any period of repetition: sync pulses, controls signals, error protection code, data transmission, checking codes to select pause for period of protection interval and radio pulses reflected from target, surface of earth or water and local objects are received during any time period from roll-out of current radio pulse to front of subsequent radio pulse. Reflected radio pulses are stored between periods. Signal of target is detected by comparing amplitude of stored pulses with preset threshold after reflected last probing pulse is received. Two monochromatic pulses are irradiated, which pulses have doubled period of repletion and have highly stable duration and period of repetition. Also radio pulses are radiated which have to be equidistant one to another, which pulses are received after they had been retranslated.

EFFECT: high noise immunity; high precision of detection and identification.
