METHOD FOR PROXIMITY-WISE TRACKING OF A TARGET BY RADIOLOCATION STATION WITH HIGH FREQUENCY OF PULSES REPEAT Russian patent published in 2005 - IPC

FIELD: radiolocation.

SUBSTANCE: method is based on tracking lateness of signal reflected by target and discontinuous change of period of pulses repeat during multiple probing of target. Method is different by recording value of periods of emitted repeat signals T_i and error ranges ε_i during each i-numbered probing of target, calculation for N last probing attempts of correlation coefficient K_N between values of error signals ε_i and period differences (T_i - T_i-1), comparison of value of correlation coefficient K_N with predetermined threshold value and if absolute value of K_N exceeds threshold, and in accordance to sign of K_N, calculated extrapolated value of whole number of emitted pulses repeat periods is decreased or increased for one unit, aforementioned pulses being contained in value of lateness time of signal reflected by target, and cyclic repeat of all operations during following target probing attempts.

EFFECT: higher precision.
