Single-pixel three-dimensional imaging for space-continuous targets based on compressive sensing

In this paper, three-dimensional imaging method for space-continuous targets based on compressive sensing is investigated to get high precision imaging especially under low signal-to-noise ratio environments. Spatial correlation characteristic is adopted to enhance the anti-noise performance of imaging and the pulse echo attenuation characteristic is evaluated to settle the overlapping echo problem of space-continuous targets. Numerical simulations are performed to indicate the availability of our method and the experiment results demonstrate the applicability in 3D imaging, which is therefore fundamental to the complicated targets detecting and imaging with higher precision in the prospective practical applications.
