老师您好,请问一下,Iwr1843Boost支持4个G的带宽,但是如图红色虚线所示,虽然总共的扫频带宽可以达到4个G,但是ADC实际采样的有效带宽为2个多G,我该如何配置chirp参数使得我的ADC采样达到4个G呢

你好,
Total Sweep BW= slop*ramp end time
valid sweep BW = slop*adc sampling time
adc sampling time=采样点数*(1/采样率)
你可以尽量让adc start time+adc sampling time接近ramp end time。注意,adc start time一定要按照建议要求设置,不能设置为0.
