摘要
随着武器装备复杂程度的增加,其信号接收通道对本身固有噪声电平范围的要求愈加严格;介绍了一种装备噪声信号处理装置,可实现噪声电平的实时监测和瞬时报警信号发生;同时可根据装备不同的工作状态调节噪声允许范围,具备本地手动调整和远程程控调整的能力;测试验证表明,装置的-3dB带宽、增益调节范围、报警信号门限等参数充分满足设计指标要求。成功地应用于在役典型装备接收通道,实践表明本装置及其设计方法具备很好的实用与推广价值。
The demands of controlling inherent noise are being strictly while performance of weapons is improved. This paper introduces a device which designed to measure noise and produce alarm. It can be controlled to adjust the noise voltage scope locally as well as far a- way. The experimentation confirms that -3 dB bandwidth, VGA range and alarm signal meet design requests. The application proves that the design described in this paper can satisfy the demands of weapons.
