METHOD OF DETERMINING RANGE TO SURFACE OF EARTH Russian patent published in 2020 - IPC G01S13/08 G01S13/10 G01S13/32 

FIELD: radar equipment.

SUBSTANCE: invention relates to radar engineering and can be used in designing various radar systems intended for determining range from a moving object to ground surface, using the principle of reflection of radio waves. Method of determining range to surface of earth, comprising using as probing signals radio pulses consisting of N monochromatic subpulses, with non-periodic phase-code internal pulse manipulation, change of carrier frequency of radio pulses of repetition period and duration from radio pulse to radio pulse, reception of signals reflected from ground surface, performing coordinated filtration of reflected signals and determining range to ground surface at preliminary stage repetition period, duration of probing radio pulses and the number of monochromatic subpulses are fixed, and detection of reflected signals is carried out simultaneously in the entire range of determined ranges with breaking the range of determined ranges to the surface of the earth into ƒ subbands, in each of which there performed is matched filtration of reflected signals.

EFFECT: shorter time for detection of reflected signals and rough determination of range to surface of earth.
