Webso NLFM is only t for single object situations. With LFM the problem does not occur since the beat frequency is unique. Saw tooth or triangle wave can be used for modulation and in this report saw tooth is considered. 2.1 The principle of FMCW radar A typical block diagram for FMCW is shown in Figure 1 [2]. FMCW radar WebMar 21, 2024 · The signal from LFM generator and Laser source is modulated using Mach-Zhander modulator and resultant signal is known as frequency modulated continuous wave (FMCW) signal hence the system is termed as FMCW photonic radar (Sharma et al. 2024). This output modulated signal is transmitted in free space using telescope to detect and …
