WebThe laser transmitter and photoelectric receiver are the core modules of the detector in a laser proximity fuse, whose performance variability can affect the accuracy of target detection and identification. In particular, there is no study on the effect of detector’s component performance variability on frequency-modulated continuous-wave (FMCW) … WebFMCW waveforms are common in automotive radar systems and ground-penetrating radar systems. How to Create FMCW Waveforms To create an FMCW waveform, use phased.FMCWWaveform. You can customize certain characteristics of the waveform, including: Sample rate. Period and bandwidth of the FM sweep.
