METHOD OF EFFECTIVE AREA IDENTIFICATION OF AIR OBJECTS SCATTERING BY ON-BOARD RADAR LOCATION STATION Russian patent published in 2017 - IPC G01S13/00 G01R29/08 

FIELD: radio engineering, communication.

SUBSTANCE: aerial object (AO) is irradiated with a sounding signal, the reflected signal is received, the power of the radiated signal is measured, the distance to the airborne object, when determining the value of the effective scattering area (ESA) of the AO for classification according to the criteria of dimension "large", "medium", "small" measuring the angle of the horizontal angle AO, measuring the amplitude of the received signal, comparing the amplitude of the received signal with a predetermined threshold, if the amplitude of the received signal is exceeded by a predetermined threshold, the device measures the power values of the radiated signal, the distance to the AO, the angle of the horizontal angle AO, the amplitude of the received signal, then the above operations are repeated until an array of at least five measured power values of the radiated signal, the range to AO, the angle of the horizontal angle AO and the amplitude of the received signal is accumulated in the mass storage device, an array of ESA values of the BO is calculated for each of the stored measurements according to a certain formula. Using the obtained array of ESA AO values and the measured array of angles of the angle AO, find the minimum and maximum values of angles of the angle AO, determine the range of the angle of the horizontal angle, then determine the average value of the ESA AO in the measured range of angles of the horizontal angle. After that, based on the ESA value obtained, the target is classified according to predetermined criteria for classifying the object as "large", "medium", "small".

EFFECT: increasing the accuracy of determining the effective area of airborne scattering.
