Background

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.
