Interference Tolerant Radar System for Self-Driving Vehicles
Tech ID: 27220 / UC Case 2016-583-0
UCLA researchers in the Department of Electrical Engineering have developed a low cost radar system that can detect up to 22 vehicles within 15 cm range.
Radar is one of the oldest and most efficient methods to detect objects. It is used in diverse applications such as detection of aircraft, ships, missiles, navigation system in vehicles and so on. However, current radar-based methods are limited by interference - the physical phenomenon of signal cancellation due to multiple signals transmitted in close proximity. It is especially important in emerging technologies such as driver-less cars that require highly accurate navigation systems. Current state of the art relies on frequency-modulated, continuous-wave radars but these are limited on the number of users that can be accurately detected and have limited range.
UCLA researchers have developed a radar system that overcomes the limitations of the current technology. It is a CMOS radar system and is tolerant to interference. It can detect signals from up to 22 vehicles in adjacent positions. Prototype tested in the lab showed an excellent range of up to 15cm.
