AWR2243: 4级联雷达mmwaveconfig.txt理解

Part Number: AWR2243

你好,

对mmwaveconfig.txt文件理解。

默认配置文件mmWaveLink_Cascade_Example/mmwaveconfig.txt中,

A
CascadeDeviceMap=15; #4个芯片工作。

B
#rlChanCfg_t:
channelTx=7; # TX_CHAN0, TX_CHAN1, TX_CHAN2开启。
channelRx=15; # RX Channel 0,RX Channel 1,RX Channel 2,RX Channel 3开启。
cascading=0; #SINGLECHIP: Single mmWave sensor application,这里什么意思?不应该是多芯片吗?

C
#rlChirpCfg_t:
chirpStartIdx=0;
chirpEndIdx=63;
profileIdCPCFG=0;
startFreqVar=0;
freqSlopeVar=0;
idleTimeVar=0;
adcStartTimeVar=0;
txEnable=1; # TX0 Enable。
#ENDs

#rlChirpCfg_t:
chirpStartIdx=64;
chirpEndIdx=127;
profileIdCPCFG=0;
startFreqVar=0;
freqSlopeVar=0;
idleTimeVar=0;
adcStartTimeVar=0;
txEnable=2; #TX1 Enable。这里要开启TX0,TX1,TX2三个通道,怎么设置?增加第3个#rlChirpCfg_t?
#END

D
#rlFrameCfg_t:
numAdcSamples=256; #帧配置中采样点数。对于复采样,为profile中采样数的2倍?
chirpStartIdxFCF=0;
chirpEndIdxFCF=11;
frameCount=100;
loopCount=64; #1帧中chirp数:(11-0+1)*64。是否正确?


整个配置文件中,
1帧的chirp数,
由D是12*64=768个。
由ABC,4个芯片开启了3个发射通道,每个通道64个chirp,1帧3*64*4=768chirp。是否这样理解?
TX2是按哪组#rlChirpCfg_t设置?或者另外加一组:
#rlChirpCfg_t:
chirpStartIdx=128;
chirpEndIdx=191;
profileIdCPCFG=0;
startFreqVar=0;
freqSlopeVar=0;
idleTimeVar=0;
adcStartTimeVar=0;
txEnable=4; #TX2 Enable开启。
#END

谢谢!
