AWR2944: abnormal noise issue

Hi Andy,

Is the customer performing 16-point FFT (1D FFT)? What is their range resolution? Is the customer using their own processing chain?

Hi Samhitha Bobba

We perform 1024-point FFT(1D FFT). The figure is enlarged partially. The range resolution is 0.624m. We use our own processing chain.

Hi Longtao,

Can you share the detection matrix over mail to Andy if possible? Can you also send a picture of the scene?

Regards,

Samhitha

Hi Samhitha

I have send Andy the detection matrix. We gather the data in our electromagnetic wave anechoic chamber. 

Hi Longtao,

Let me check the detection matrix whenever Andy shares it with me.

Hi Longtao,

In the meantime, can you confirm if you are testing in a static environment? The target detected in 9th/10th rangebin has different velocity. Also what do you mean by "angle reversal"? There is another target detected at 13-15 rangebin which also has different doppler. Can you describe about the scene?

Samhitha

Hi Samhitha,

I can confirm that we test in a static environment. We use step frequency waveform.

This is the test room。

Hi Longtao,

Andy just shared the detection matrix. Let me take a look and get back to you.

Samhitha
