Radar is one of the most popular new technologies for next-generation auto safety systems, with hardware and software companies incorporating it into their products.

Intel subsidiary MobilEye is developing chips equipped with radar antennas, while General Motors has invested in Oculii, a math-and-software startup that configures signals from automotive radar systems through machine learning.

Software firm MathWorks is developing algorithms that enable automakers to combine data from radar and other sensors into an accurate picture of a vehicle's surroundings.

Oculii's technology upgrades the resolution of radar images by changing the waveform of radar signal transmissions from the car; MobilEye said its systems leverage artificial intelligence software to process the noisy signals received by chips to identify pedestrians.
