FIELD: physics; measuring.
SUBSTANCE: prospective invention concerns the radar-tracking measuring technics and range-frequency and also in radar measuring equipment and can be used in radar stations with the continuous periodic radiation with any triangular frequency modulation (FM), measuring a standing of the purposes in coordinates. The specified effect is reached at the expense of generating of digital read-out during the fixed moments of time, their transformation to discrete analogue readout and low-frequency filtration of discrete analogue readout with reception of analogue quarter-phase (sinus and cosine) FM on a video to frequency of signals with triangular frequency modulation with a demanded continuance of modulation and with deviation in m time of smaller demanded deviation of a sounding signal, transport quarter-phase FM on video frequency of a signal on higher carrier frequency with the help of the quarter-phase balancing mixer, multiplication of frequency of the gained signal in m time, amplification of a signal to demanded power in the given frequency band.
EFFECT: measurement accuracy increase in radar stations with periodic frequency - modulated (FM) signal with any triangular modulation at the expense of maintenance of high linearity of change of a carrier frequency in time with possibility of coherent accumulation between periods.
