A new method of passive bearing estimation based on compressed sensing

摘要

A hardware implementation of compressed sensing is performed in acoustics. Unlike most of the optically compressed imaging implementations, such as the single-pixel camera, the scattering of scatters is substituted for a carefully engineered Digital Micro-mirror Device. An experimental design is carried out to prove the feasibility of passive direction-finding with only a single acoustic receiver. It is demonstrated that the idea of compressed sensing may also bring revolutionary influence on acoustic detection systems.
