Low Cost Millimeter Wave Radars in the automotive field

The first practical radar applications date from before World War 2, but radar techniques are widely used nowadays in a large number of mostly military or ´professional´ civilian applications. They make use of extremely high frequencies generated by traditionally expensive technologies. Recent advances in electronics components, in terms of speed of development and cost, allow us to predict radar being used for civilian mass-market products, such as motor cars. In particular, these advances concern RF components in the millimeter wave bands with high-speed, wide-range digitization systems and digital signal processors
