AWR1843: Interference mitigation in frequency domain

Part Number: AWR1843

Hello!

I am new to Code Composer Studio and I have a project in that I have to implement a method for interference mitigation in the frequency domain, using STFT(short time fourier transform).  I was trying to modify the demo for victim radar presented in mmwave_platform_1_2_1\labs\interference_mitigation, but I saw that this has an implementation in the time domain and that is running on DSP but i could not to did this.

Could you suggest to me how I can implement a STFT starting from this Demo project?

Looking in this project  I observed that the range profile is calculated using HWA. Is possible to implement the STFT using HWA? (I observed that there is not a classical FFT applied in order to obtain range profile).

Thank you for your support!
