Real-time object tracking using a leaky THz waveguide

Our research has involved an exploration of the use of the leaky-wave
transmitter as a broadband impulse radar, for complementary sensing capabilities. It is clear that such sensing functionalities will be a critical part of future terahertz LANs. There is an obvious advantage to using the same device to carry out both sensing and other network functions. We have demonstrated the detection of multiple targets within the broadcast sector of a leaky-wave antenna, with millimeter-scale accuracy in both range and cross-range, and with the capability for near-real-time (e.g., 5 Hz) measurement updating. Most interestingly, we have shown that non-line-of-sight radar is also feasible using this approach.
