Abstract
A drone detection, identification and location system and method may illuminate a target with one or multiple selected radio-frequency (RF) carrier frequencies. Both direct emissions received from the target and re-emissions generated by the target may be processed to determine whether the target is a drone. The re-emissions may be generated by circuitry of the target resulting from the illumination with the one or multiple RF carrier frequencies. The re-emissions may comprise cross-modulation products (CMPs) including forced non-linear emissions (FNLEs). The direct emissions and the re-emissions may be processed to generate an RF signature for the target. The target may be determined to be drone and the type of drone may be identified based on the RF signature.
