Design of harmonic radar based on dual-transmitter and dual-receiver mechanism

Abstract

Harmonic radar is a kind of radar that uses the higher-order harmonics reflected by the target for nonlinear target detection. Eavesdropping equipment usually has non-linear devices, so harmonic radar can be used in the field of anti-investigation to detect voice recorders and eavesdroppers. In this paper, a kind of harmonic radar based on dual-transmitter and dualreceiver is designed to meet the needs of anti-investigation of eavesdropping equipment, and three kinds of electronic targets such as recording pen are tested and verified. The verification results show that the device can detect nonlinear electronic targets well.
