IWR1843BOOST: TDM-MIMO SAR成像问题

Part Number: IWR1843BOOST
Other Parts Discussed in Thread: DCA1000EVM, AWR1642, AWR1843

为了实现如图所示中的单通道成像

设置雷达采用三发四收

(1)profile配置为

(2)chirp配置参考DCA1000EVM: AWR1642EVM mmWave studio TDM or BPM MIMO setting - Sensors forum - Sensors - TI E2E support forums

成像结果与实际不符,请问:

(1)这种chirp配置方法是否有问题?

(2)采用TI提供的matlab读取程序可以正确读取4个接收天线的数据,请问在TDM-MIMO下单个接收天线的数据存储格式是怎样的?
