WebLFM waveforms can reduce side lobe level by -13dB by applying various methods but at the cost of reduced SNR. Therefore to overcome this we opt for a new waveform NLFM which can do the same with good SNR and low cost. In the next section NLFM waveform is thoroughly described. 2.2 Non linear frequency modulation (NLFM) ... WebFMCW radar ( F requency- M odulated C ontinuous W ave radar = FMCW radar ) is a special type of radar sensor which radiates continuous transmission power like a simple continuous wave radar ( CW-Radar ). …
