生长行为及力学性能的影响
And the waveform of the transmitted signals was designed based on the target distance ( 5 ~ 50m ) . the waveform is triangular fmcw with central frequency at 6ghz , modulation bandwidth 100mhz , modulation period 10 s , step frequency 0 . 2mhz , and step time 10ns
在此基础上,设计发射信号波形参数为三角形调频连续波,中心频率6ghz ,调制带宽100mhz ,调制周期10 s ,步进频率0 . 2mhz ,步进时间10ns 。
It's difficult to find modulation period in a sentence. 用modulation period造句挺难的
