Cost-Minimized 24 GHz Pulse Oscillator for Short-Range Automotive Radar Applications

This paper reports on the design of ultrawideband 24 GHz pulse oscillators developed for automotive radar applications. Due to system considerations (range resolution, dynamic range), such oscillator modules need to generate ultra-short coherent pulses. Measurement results of prototype oscillators demonstrate +5 dBm peak output power, less than 1 ns pulse width and excellent coherency. The oscillators were applied in a radar sensor and good performance was achieved.
