MMWCAS-RF-EVM: How far is the closest test distance

Hi,

We encourage the customer to review the related TI design:

Especially the TI Design Guide

Thank you

Cesar

Hi Cesar,

Thanks for your response.

Customer reviewed TI Design Guide, But he didn't find the information he wanted. 

In addition, he would like to know:

• What is the specific impact of ADC sampling rate on radar?
• Are there more points obtained by sampling objects?

Best regards,

Annie

Hi,

Here are some answers to the questions

Question: What is the closest test distance of mwcas-rf-evm and mwcas-dsp-evm cascade board?

Answer: In our testing, the closest test distance was around 10m.

Question: What are the advantages of mwcas-rf-evm and mwcas-dsp-evm cascade boards compared to previous boards of the same type?

Answer: The advantage of a cascade systems is the increased number of Rx/Tx channels. This results in longer range and higher angular resolution

Question: Related parameters of MWCAS-RF-EVM

Answer: parameters are provided in the TI Design User Guide

Question: What is the specific impact of ADC sampling rate on radar?

Answer:

Please see the Introduction to mmWave sensing training

ADC sampling rate is discussed in Slide 15

Question: Are there more points obtained by sampling objects?

Answer: More points are obtained because of higher number of Tx (more power) and higher number of Rx (higher angular resolution)

Thank you

Cesar
