          Abstract

          Autonomous vehicles are predicted to dominate the transportation industry in the foreseeable future. Safety is one of the major challenges to the early deployment of self-driving systems. To ensure safety, self-driving vehicles must reliably sense and detect humans, other vehicles, and road infrastructure accurately, robustly, and timely. In this paper, we describe the design of REITS and simulate its operation. REITS is an antenna system for blind beamforming that uses constructive interference to return an enhanced radar signal in the direction of the radar emitter. The signal-to-noise ratio (SNR) of the return signal is further enhanced by canceling out irrelevant reflections, using destructive interference. Combining blind beamforming with the enhanced SNR improves the detection distance of a self-driving car radar by a factor of2.82.
