METHOD OF PASSIVE SINGLE-POSITION-DIMENSIONAL DIFFERENTIAL-DOPPLER LOCATION OF A RADIO-EMITTING OBJECT ROVING IN THE SPACE AND A RADAR LOCATION SYSTEM FOR THE REALISATION OF THIS METHOD Russian patent published in 2017 - IPC G01S11/00 G01S11/10 

FIELD: radio engineering, communication.

SUBSTANCE: is reduced, knowing the modulation type, the carrier frequency of the received signal is formed at the appropriate times and storing the values of its counts represent the results as appropriate depending on the time, filter the resulting dependence to reduce measurement errors, receiving averaged relationship is selected from addiction and fixed at predetermined times required for computing the values of the carrier frequency of the signal received interpolated averaged angular dependence of the azimuth and elevation angle to calculate the T intervals corresponding to the passage of an object azimuthal sectors, increment calculated Doppler frequency shifts the received signals, interpolated and calculated values extrapolated observation interval ranges, determine the criterion for the preservation of the hypothesis on the uniform and rectilinear motion of radio-emitting objects (RIO), determine the slope ranges and heights from the corresponding formulas, based on the corresponding calculations, plot the trajectory of the RIO movement in space on the observation interval, verifying the validity of the hypothesis of uniform and rectilinear RIO motion, The device implementing the method is an angular-difference-Doppler radar system performed in a certain way.

EFFECT: ability to measure the direction of movement of radio-emitting objects, the modulus of linear velocity, slope distance and trajectory of movement of radio-emitting objects.
