Abstract
The present disclosure relates to radar signal processing, and a harmonic radar based on a field programmable gate array (FPGA) and deep learning. Specifically, a signal processing module generates a baseband linear frequency modulation (LFM) signal, converts the baseband LFM signal into an analog signal, and mixes the analog signal with a local carrier frequency signal to obtain a radio frequency (RF) transmitting signal. A second-harmonic signal/a third-harmonic signal is generated after the RF transmitting signal irradiates a target, and is transmitted to a second-harmonic receiver/a third-harmonic receiver correspondingly; after undergoing low-noise amplification and filtering by the corresponding harmonic receiver, the second-harmonic signal/the third-harmonic signal and a corresponding local oscillator signal are demodulated to obtain an echo baseband signal; and the echo baseband signal is amplified and sent to a signal processing module for processing after being quantified and converted by an analog-to-digital converter (ADC).
