Simulations of novel radiometer systems using compressed sensing

Abstract

In this paper, a novel radiometer system using compressed sensing technique is simulated. Millimeter-wave radiometer is a high-sensitivity noise power receiver that can detect the microwave radiation from objects. Millimeter wave radiometer is one of the key technologies in millimeter wave passive detection and imaging. The novel system this paper proposed using compressed sensing is a focal plane system, which simultaneously receives signals through multiple feeds. Each feed receives the corresponding pixel point of millimeter wave radiation energy. The system achieves the similar function of the dam-board by on-off the switch. The system reduces the number of receiver channels via the use of compressed sensing. The proposed system not only overcomes the shortcomings of the traditional systems, but also recovers the image according to the theory of compressed sensing. The system performance is validated through simulations.
