High performance automotive radar systems are currently under development for various applications. Comfort systems like Adaptive Cruise Control (ACC) are already available on the market as 77 GHz radars. Target range and velocity are measured simultaneously with high resolution and accuracy even in multi-target situations but the measurement and processing time to detect the relevant object is approximately 100 ms. This paper describes a new waveform design for automotive applications based on CW transmit signals which lead to an extreme short measurement time. The basic idea is a combination of LFM and FSK CW waveforms in an intertwined technique. Unambiguous range and velocity measurement with high resolution and accuracy can be required in this case even in multi-target situations. After an introduction into FSK and LFM waveform design techniques in chapters 2 and 3 the combined and intertwined waveform will be described in detail in chapter 4.
