资料介绍

为了提高混合辨识型便携侦察雷达的易用性和可操作性,设计了语音识别辅助装置。以SPCE061A音频信号微处理器为核心,利用数字信号处理技术,通过音频线获取雷达的音频段多普勒信号,再经过A/D采集成数字信号,将此数据预处理,再进行自适应滤波,消除背景噪声,采用分段FFT转换,判别信号类型,完成对便携雷达语音辨识整体设计。所设计的电路,实际测量表明,改善了雷达分辨率,提高了雷达辨识的精确度。

The voice identification device is designed to improve the usability and operability of the hybrid-identification reconnaissance radar for individual use. The SPCE061A audio signal microprocessor is used as the core, and the digital signal processing technology is used to get audio segments Doppler radar signal through the audio cable, and then through the A/D acquisition to get a digital signal, Then The data is preprocessed and then adaptively filtered to eliminate background noise;The segmented FFT transforming is used to identify the signal type and thus complete the overall design of radar voice recognition for an individual soldier. The actual measurements showed the design of the circuit improved radar resolution and improved the accuracy...
