Many important modern-day applications such as autonomous driving, traffic monitoring, surveillance etc. warrant the use of Imaging radars - that offer high detection accuracy and resolution while maintaining privacy. Imaging radars need to act as more than 4-D imaging devices that not only detect range, Doppler and direction-of-arrival (in Azimuth and Elevation) with high accuracy, but also provide information on object classification, etc. Considering state-of-the-art IC, MIMO antenna array and signal processing systems that reinforce each other in bringing out high resolution imaging at optimal cost.
