Radar system and method combining FMCW and FM pulse compression

摘要

Systems and methods for providing an efficient radar system that can operate at both near and far ranges. An exemplary radar system includes a controller that generates a clock signal and a mode signal, a transmitter with a synthesizer, and a dual-mode transmitter. The synthesizer and the transmitter generate a signal in a first or a second mode (frequency ranges) based on the clock or mode signals. An antenna transmits the generated signal and receives a return signal based on the transmitted signal. A receiver processes the received return signal according to the first or second mode, based on the generated at least one clock signal or mode signal. A processor determines existence of a target included in the processed return signal. An output device (such as a display device) outputs a presentation based on the determination. The system operates in FMCW or pulse modes.
