Underground Space Detection System Based On WOLA Structure

Weak signal detection capability and real-time signal processing capability is significant for the underground space detection system. In this paper, an underground space detection system based on the channelization algorithm is designed. Through the channelization algorithm based on the weighted-overlap-add (WOLA) structure, the system can detect four weak signal energy values of different frequencies at one time. Simulation and experimental results show that compared with traditional detection methods, the system has a breakneck processing speed, and the weak signal detection ability can be improved.
