Frequency modulation continuous wave (FMCW) is often applied in miniature synthetic aperture radar (MINI SAR). FMCW SAR sends linear frequency modulated (LFM) continuous wave signal with wide band, and the receiving echo of targets mixes with the sending signal. Therefore, the echo for imaging processing can be sampled in intermediate frequency (IF) band with low sampling rate, and the system can...
For recognition of individual characteristics of radar emitter in a complex electromagnetic environment, we propose a new thinking of using digital channelized receiver to receive the Intermediate Frequency(IF) radar signal, and considering the extracted front edge waveform of pulse envelop of radar signal as the individual characteristics of emitter. To solve the problem that it is not conducive...
