Hello,
For my thesis as a graduate, I need to explore the feasability of a FMCW radar system with a rather challenging requirement of detecting very fast targets (>800m/s). This necessitates extremely fast and linear chirps to achieve the necessary range resolution and update rate. More specifically, I'm looking to generate sawtooth chirps around 6 GHz, spanning at least 200 MHz, with a sweep time of less than 15 µs.
Are there specific ICs or architectures that are best suited for this speed and frequency range? I'm particularly interested in knowing about any ICs capable of generating such chirps. The closest candidate so far being the AD4159 from analog devices.
Any insights, recommended ICs or warnings based on your experience would be greatly appreciated.
Thanks in advance for your help!
