1) pulse bandwidth
脉冲带宽
2) broadband pulse
宽带脉冲
1.
It is found that they are the same in the neighbourhood of z-axis for narrowband pulses, but in the case of broadband pulses, singularities emerge near z-axis for pulsed beams obtained by using complex amplitude envelope representation and only complex ana.
数值结果表明脉冲光束为窄带时,在传输方向轴中心的一定范围内两种解是一致的,而对于宽带脉冲光束,复振幅包络解在轴中心较近的距离即表现出奇异性,复解析信号解才是符合物理意义的表示式。
3) IR-UWB
脉冲超宽带
1.
Performance Analysis of the ALOHA IR-UWB Network;
ALOHA脉冲超宽带网络的性能分析
2.
A novel gated integrating method in IR-UWB application;
一种应用于脉冲超宽带的新型门控积分方法
3.
IR-UWB Signal Generation, Control and Detection;
脉冲超宽带信号产生、控制与检测
5) wideband mono-pulse
宽带单脉冲
1.
There is a contracted introduction of the principle of wideband mono-pulse radar and the method of deconvolution in measuring the difference of time delay in mono-pulse sum and difference channels.
宽带单脉冲三维成像雷达具有很高的距离分辨率,差信号经过相对于和信号的归一化处理后就能提供目标方位、俯仰信息;但和差通道微小延迟差可能对角度测量造成较大影响。
补充资料:宽带和窄带业务
宽带业务是相对窄带业务而言的,一般来说,对于速率低于2Mb/s的通信业务统称窄带业务,如电话网、N-ISDN所提供的业务。对于高于2Mb/s的通信业务,如帧中继业务、视频点播、ATM业务、TV会议等称为宽带通信业务。 目前投入应用的宽带接入技术主要有两种:ADSL和FTTX+LAN。
