| 摘要: |
| 在现有的器件水平下,采用多通道并行采集再进行数字信道化的方法对接收信号进行并行处理,可以完成极高频/超高频(EHF/SHF)频段战略战术通信中跳频带宽高达数吉赫、跳速高达每秒数万跳的超宽带快速跳频信号实时检测;同时,采用多通道高速采集、海量存储方法存储海量数据,再采用相应跳频信号分析方法可以完成信号分析和解跳解调以及信号解译。研究实践证明,该方法是目前进行超宽带快速跳频信号进行侦察的有效手段。 |

| Abstract: |
| Under conditions of current devices,multi-channel sampling and digital channelizing enables real-time detecting the ultra wideband(UWB) high speed frequency hopping(FH) signal whose bandwidth of frequency hopping is up to serveral Giga-Hertzs and the hopping rate is up to tens thousand hops per second in strategitic and tactic communications of EHF/SHF(Extremly High Frequency/Super High Frequency)band;at the same time,multi-channel high-speed sampling and magnanimity storing enables the signal analyzing,de-hopping,demodulating and signal decoding utilizing corresponding FH signal analysis methods.This communication reconnaissance way to UWB high-speed FH signal has been proved an effective measure. |
