Radar signal quality for the automotive industry

Automotive radar signal analysis and generation

Signal analysis for high-frequency radar signals

The trend of increasing bandwidths – today up to 4GHz – allows a better object recognition than ever before. Rohde & Schwarz solutions characterize radar signals and components to improve the reliability of autonomous driving vehicles.

Due to the way radars operate, using radar based sensors to recognize the environment will only be as precise as the transmission signal. It is therefore very important to have a linear, low-noise signal for FMCW radars. The Rohde & Schwarz Signal and Transient Analysis Software ensures that these high requirements for the transmission signal are met.

Important key parameters such as chirp rate, length and deviation are automatically analyzed and presented in an easy-to-understand table. The individual chirps and their parameters are also displayed graphically, enabling intuitive and fast debugging.
