Hello,TI's expert
When i develop base on AWR1843Boost,and i meet a problem.We have two mode,they are short range mode and long range mode.
And i config the profile/chirp/advanced frame.The profile is same,short range mode chirp is 0 to 255,open with tx1,long range mode is 256 to 511,open with tx2 && tx3.
When I run these two modes separately,the RDM is correct.See as follow:
However run together,first subframe1(short ) then subframe2(long ),the RDM data will be error,the doppler dim will expand .See as follow:
TX1 turned on when I configured long range mode as well as short range mode,the error will disappear.So in long range mode I can't turn on any other antenna except tx1.I also verified this in MMWave Studio.Where is the problem?Is it the limitations of the chip itself or the interference between the transmitting antennas?
