[Concept of bi-static radar (left) and multi-static radar (right)]
Radio detection and ranging (Radar) is a technology detecting the existence of targets and estimating the angles and directions of the targets. As shown in the figure above, the radar is based on the analysis of the received signal which is the transmitted signal reflected by targets. The major application of radar includes military, remote sensing, air traffic control, law enforcement and highway security, aircraft safety and navigation, ship safety, space, and etc. The AiSLab studies signal processing for radar which includes detection and estimation theory for target detection and range/angle estimation. In addition, the AiSLab works on proof-of-concept implementation of radar signal processing using drones and software-defined radio.
