METHOD OF DETERMINATION OF PARAMETERS OF MOTION OF LOCATION OBJECT Russian patent published in 2001 - IPC

FIELD: location and navigation fields; pulse methods of determination of coordinates and parameters of motion of location object; location systems for determination of range rate and acceleration relative to motion of object for avoidance of collision of location object and active monitoring point. SUBSTANCE: method includes simultaneous radiation at preset period of pulse burst by active monitoring point at different propagation velocity, reception of pulse burst reflected from location object, determination of distance to location object by measured delay time of echo signal during its reception relative to moment of radiation of burst and determination of range rate of object. During reception of burst pulses reflected from object, difference between delay times of first echo signal (which is faster) and following echo signal (which is not so fast) is determined and change in distance to object between moment of faster echo signal and following echo signal (which is not so fast) with location object is calculated; according to magnitudes thus obtained, its range rate at given section of motion is determined, after which range rate of location object motion is determined between moment of its contact with above-mentioned second pulse of burst and following third pulse; radial-path acceleration is found by difference of measured range rates, after which permissible parameters of relative motion of active monitoring point and location object are estimated and command signals are formed for change of number of pulses in burst being radiated. Besides that, in estimation of determined magnitudes of distance, rate and acceleration as parasitic parameters of relative motion of active monitoring point and location object, command signals for control of motion of location object or active monitoring point are additionally formed. EFFECT: enhanced accuracy of determination of location object motion parameters; extended functional capabilities due to fast measurements of these parameters and additional determination of range. 2 cl, 1 dwg
