Analysis on the Effect of Spurious Signals of Transmission and Local Oscillation Signals in a Compact Radar

The spurious signals of the transmission signal (FTX) and local oscillation (FLO) for a receiver are factors that reduce SNR(signal-to-noise ratio) performance radar. In particular, with high-power level causes radar to falsely indicate target. However, emissions frequency synthesizer unavoidable because nonlinearity RF active elements on FTX FLO paths. this study, requirements provided ensure SNR compact Consequently, power should be lower than −55 dBc −28 according offset in FMICW mode. addition, it −50 −40 within linear modulation bandwidth (LFMM) MPRF mode, out LFMM do not impact processing results.
