AWR1243： raw data stored file format

Hello，

I have used DCA1000+AWR1243 capture raw data and got adc_data_Raw_0.bin. I see from "DCA1000EVM Data Capture Card User's Guide" that in raw mode, the file is stored in the following format:

My question is, what is the data of a sequence number represent？how many sequence numbers does a chirp and a frame contain？and how are they placed?

Thanks！
