WebJul 5, 2024 · Compared with the two existing methods, the chirp radar with stepped frequency has the constant bandwidth and pulse width, which means high range resolution and short blind range. In the meantime, stepped frequency can be achieved more easily. 4 Numerical computation WebA measurement of the quality of a complete radar transmitter can be made using the FM chirp from the radar's own exciter as the swept RF source. In this manner, the quality of the generated chirp as well as all modules that the chirp passes through will be tested together as a complete assembled radar.
