IWR1443BOOST: 斜率Slope

Part Number: IWR1443BOOST
Other Parts Discussed in Thread: DCA1000EVM

你好,

我使用IWR1443BOOST+DCA1000EVM对运动目标的轨迹的测量,理论上来说,为取得更高的距离分辨率,雷达信号带宽越大越好,因而在对chirp进行配置时,在ramp time已确定的情况下,chirp的斜率Slope越大则雷达扫频信号带宽越大,信号的距离分辨率越好。

我现在有一个担忧,斜率取得越高,是否会对生成的chirp信号线性造成影响,即所生成的线性信号的线性质量下降,因而导致实际应用的效果并不好?该如何避免这种情况?
