Other Parts Discussed in Thread: TIDEP-0092
We are using AWR1642 for Vehicle Radar and now simulating reference design code (TIDEP-0092) SRR part with matlab currently.
Here are some questions about algorithm in reference design and SDK library function
1. Due to multiple received antenna,we have multiple ADC raw data, How to deal with the data with different antenna (data fusion) , if the reference design do some processing between antenna,what method is applied?
2. Does the reference design code do the digital beamforming ? (I have this question due to the sharp antenna pattern but still has the FOV 120 degree)
3. In power detection mechanism, CFAR has the parameter const1 and const2, how to determine in SRR case ? In most case is given probability false alarm rate and we can calculate the threshold value ?
4. How does peak grouping works in SDK library ? What is the definition of detection matrix ?
5. In reference design, Fourier beamforming method is applied for DoA estimation, what angle steps and angle interval is applied ?
6. In reference design, how to calculate frame length in SRR design ? (I tried to calculate by: (effective chirp time + idle time )*number of chirps + (effective chirp time + idle time )*number of chirp) fast chirp/slow chirp (51us +3us)*64+(51us +14.8us)*64 .The results does not match frame length mentioned above.
7. In SDK library, there is a function called extendedmaxvelocity, I have some question about what SDK user guide mentioned. As follow:
