An Injection-Locked-Based FMCW Transmitter With Synthetic Bandwidth Technique


An injection-locked-based frequency-modulated continuous-wave (FMCW) transmitter using a synthetic bandwidth technique is presented. A wideband chirp is synthesized by combining the up-converted narrowband chirp with different adjacent carrier frequencies. This is achieved by mixing a narrowband direct digital synthesis chirp with a fast-switching… (More)
