FIELD: radio engineering, communication.
SUBSTANCE: in the proposed radar location method for detecting aircrafts, probing radio signals are emitted alternately with linear polarization and with quadrature polarization, and each radiated probing radio signal with quadrature polarization is phase-synchronous with the previous linear-polarizing probing signal. After the spectra comparison of the demodulated reflected radio signals with linear polarization and reflected radio signals with quadrature polarization, it is judged that the aircraft is detected by the presence of the value multiplicity of their amplitude modulation periods.
EFFECT: possibility of detecting unobtrusive aircrafts.
