Hou Chaohuan was born in Zigong on September 29th, 1936. He has been smart and studious since he was a child. After graduating from Shuguang Middle School, he was admitted to the Physics Department of Peking University with excellent results, and graduated from 1958. Hou Chaohuan is a famous expert in information, signal processing and acoustics in China, an academician of China Academy of Sciences, director of Information Science Department of National Nature Conservation Foundation, researcher, deputy director and doctoral supervisor of Institute of Acoustics, Chinese Academy of Sciences. In addition, he also served as the vice chairman of the Chinese Acoustics Society and the vice chairman of the Signal Processing Society.
In the research of underwater acoustic engineering, Hou Chaohuan presided over the research of "Measurement System for Statistical Characteristics of Underwater Acoustic Signal Fluctuation", which promoted the research of underwater acoustic signal field, noise and reverberation field. A phase-shifted multi-beam array signal processing system is proposed, and its comprehensive analysis, theoretical calculation, parameter selection, optimal design and performance estimation are given. An intelligent underwater acoustic signal processing system is completed, which enables the system to match underwater acoustic signals and achieve the best working state and processing effect. After the system was successfully applied to engineering projects, it received remarkable social and economic benefits. According to the international requirements for ultra-high speed computing, Hou Chaohuan began the research on parallel array processing in 1980s, and then integrated the parallel processing system into a single chip. The research of VLSl signal processing was first conducted in China. Firstly, the DSP- 1 array signal processor is completed, and the fixed-point operation speed reaches 1.32 billion times per second. The floating-point operation speed reaches 360 million times per second. Several ultra-high-speed DSP special chips have been developed one after another. The single chip T contains 15 operation nodes, and the multiplication speed of the single chip reaches10 billion times per second.
Since Hou Chaohuan served as the deputy head of the "863" information acquisition and processing expert group from 65438 to 0987, he has completed the research on the theory and methods of multi-domain signal processing, with many breakthroughs and innovations, including new Fourier transform algorithm and adaptive array processing.
