Abstract	The FMCW-Radar-Principle is widely used for short range radar systems. The basic idea for FMCW-Radars is to generate a linear frequency ramp as transmit signal. There are too widely used principles for Range-Doppler-Processing: Generation of ramps with different slopes and generation of a sequence of short ramps processed by a two-dimensional FFT. The developed ramp generation sequence also applies two-dimensional Fourier transforms, but allows to reduce the baseband bandwidth. The principle can be also regarded as an extension of a Frequency Stepped-CW-Radar with intertwined ramps. In the following the method is derived for systems with and without I/Q-Demodulator and first measurement results on a 24GHz-System are presented. The waveform generator has been implemented on a FPGA.
