你好,我需要如下图所示的波形,以下图波形循环发射,在mmWaveStudio中如何配置呢,谢谢!
你好,
论坛中提到需要在Frame Configuration, Sub frame configuration and Subframe Start Configuration中设置,我将我的波形的一个frame分成2个subframe,第一个subframe为128*3部分,第二个subframe为16个chirp部分。
(1)我在sensorConfig中完成profile和chirp的配置后,切换到Advframeconfig中配置如下图,这样配置是正确的吗?
(2)然后在Subframe Start Configuration中按Set出错如图2,是什么原因呢?
(3)在Advframeconfig完成配置后,该如何发射波形呢?
若回到sensorConfig中发射,波形会按照sensorConfig中的frame的配置发射,并未调用Advframeconfig中的subframe配置。
谢谢。
你好,
在radar studio中,我没有试过。
在OUT-OF-BOX demo中,配置如下,供参考。
谢谢

你好,
sensor config一页,有一个trigger frame,有试过吗?
谢谢
