Hallo ,i have Pulse Sense2go and i want to measure the distance using matlab . I need your help . I have already a programm that measure the velocity but i need the distance. Im searching for solution. Thank you

Dear Hannibal3011,
The Sence2Go demo kit uses a Continuous Wave Modulation of the HF-signal. With that modulation you can, based on the Doppler effect) only measure velocity and the direction of motion, like approaching and departing.
In case you need the distance to an object, you need to consider to used FMCW modulation.
see e.g. https://www.radartutorial.eu/02.basics/Frequency%20Modulated%20Continuous%20Wave%20Radar.en.html
Infineon offers here also solutions and demo kits, for 24GHz and 60GHz for consumer applications, but also other frequencies for automotive applications.
for 24GHz a good starting point would be the Distance2GoL Demo Kit: https://www.youtube.com/watch?v=kjjx9z90vxE
or for 60GHz the BGT60TR13 (https://www.infineon.com/cms/en/product/sensor/radar-sensors/radar-sensors-for-iot/60ghz-radar/bgt60...)
In FMCW the resolution of the distance depends on the bandwidth you can use. in 24GHz the band is smaller, but the possible range is higher. While in 60GHz the distance resolution is higher, but the range of RF waves is shorter.
So you need to think about your application requirements and needs.
Best Regards
Michael
