工程师,你好,在对chirp及frame进行设置时,
idle time为100us
ADC start time为10us
ramp end time为60us
sample per chirp是256
chirps per frame是32
Sample Rate是6.25Mbps
chirp Slope是20MHz/us
frame periodicity是33.3ms
天线模式为2发4收。
我的问题是,chirp带宽是多少?而采样后的ADC数据的真实带宽是多少?

请看下面帖子里的公式。
B = S * Tadc * Nadcsamples
S = frequency slope
Tadc = ADC sampling period (1/ADC sampling frequency)
Nadcsamples = # of ADC samples
