METHOD FOR ITERATIVE MEASUREMENT OF MISMATCH IN TWO-DIMENSIONAL TRACKING SYSTEMS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2020 - IPC G01S13/66 

FIELD: measurement technology.

SUBSTANCE: invention relates to systems similar to radar tracking systems, to a method for iterative measurement of mismatch in two-dimensional tracking systems and a device for its implementation and can be used in automatic two-dimensional television tracking systems, measuring mismatch in two coordinates, namely television viewers, for example, in robotic systems of agriculture. Technical result consists in improvement of accuracy of mismatch detection on both channels Y and Z, and, as a result, reliability of monitoring object tracking. Method involves multiple correction of error errors by iterative method δ_i^* by their calculation by formula δ_i*=|y_{subtract i}·z_{subtract i}|, where y_{subtract i} is mismatch value in channel Y at i-th iteration step, z_{subtract i} is mismatch value in channel Z at i-th iteration step. Error estimation errors δ_i^* are added to results, obtained at previous steps of iteration—to error term magnitude signals modules in each channel |y_{subtract i}| and |z_{subtract i}| taking into account mismatch direction. Device comprises a video amplifier, a threshold device, a standard pulse generator, a delay line, a recording unit, a control unit, memory units, a parameter measuring unit T, intended for determination of height T of a packet of pulses of a reference digital loop of a tracking object, multipliers, low-pass filters which extract the required signal component, subtractors, functional converters, performing primary operations for compensation of errors in determination of mismatch in measuring channels Y and Z, unit of iterations.

EFFECT: method is proposed for iterative measurement of mismatch in two-dimensional tracking systems and device for its implementation.
