实时频谱仪在雷达对抗中的应用

着重论述了雷达信号的捕获和脉内信息的分析。使用实时频谱分析仪(RTSA),可以实时捕获瞬态脉冲,为雷达信号的识别和分选提供了有利的工具。RTSA的瞬时信号测试功能可以提供其他分析仪上无法提供的显示性能洞察力和分析能力。RTSA不但能够像普通频谱仪一样测量雷达信号的频率和功率信息,同时数字荧光显示技术DPX和强大的触发功能可以对特定的脉冲进行发现和捕获,并分析相位参数、及频率参数等。帧重叠快速傅里叶变换、频率模板触发(FMT)和3 ns的时间分辨率、其独有的脉冲自动分析测量软件,使得可以全面的对复杂调制脉冲进行分析。不论是调试自己的雷达、EW或ELINT系统,还是进行雷达信号的侦察和识别,RTSA都提供了无可比拟的高效性能。

Application of Real-time Spectrum Analyzer in Radar Countermeasure

The document emphasizes discussing the capture of radar signal and analysis of burst information.With the RTSA,the transient burst can be captured real-time,which provides the advantageous tool to identify and select the radar signal.The function of testing transient signal of RTSA can provide display performance insight and analysis capability that can't be provided by other analyzer.RTSA can not only test the frequency and power of radar signal as well as ordinary analyzer,with DPX display technology and powerful trigger function,but also discover and capture the specific burst to analyze some important parameters such as phase,frequency.By the function of frame overlap FFTs,frequency mask trigger(FMT) and 3 ns time difference and special burst automatic analysis software,RTSA can wholly analyze complicatedly modulated burst.Either debugging own radar,EW and ELINT system or discovering and identifying radar signal,RTSA can both provide infinitely high efficient performance.
