METHOD OF DETERMINING RANGE AND/OR SPEED OF REMOTE OBJECT Russian patent published in 2010 - IPC G01S17/50 G01C3/08 

FIELD: physics.

SUBSTANCE: method involves probing an object by sending a series of n laser pulses to it and determination in each i^th probing of the time interval t_i and between moments of emission of the laser pulse, and reception of radiation reflected by the object. During each probing, current time values T_i are determined and recorded and values of time intervals t_i measured in the series of probes are recorded. For each probing, range readings R_i=c·t_i/2, where c is the speed of light, are determined. The obtained sample values of R_i are interpolated with a linear function of the type R*(T)=R*₀+V*T, where R*₀ is the range estimation at the initial time of measurement period, V* is the estimation of average speed of the object during measurement, T is the current time. A value ΔR of the permissible deviation of measurement values from the interpolation function is set. Further, the moduli ΔR_i=/R_i(T_i)-R_i*(T_i)/ of the deviation of measurements R_i(T_i) from the corresponding interpolated values R_i*(T_i) are determined. Measurements for which ΔR_i>ΔR are canceled and the remaining sample values of range are interpolated again using a function of the type R**(T)=R**₀+V**T, from which improved values of range and speed of the object are determined.

EFFECT: increased reliability of measurement results.
