I’m working on a problem where I have to build a speed detector using a hardware circuit with a microcontroller. I will be using a radar motion detector module to do this. I have contacted the manufacturer B+B sensors for information regarding the application circuits with no reply as yet (https://shop.bb-sensors.com/out/media/Datasheet_RADAR-IPM-165_DBE_Rev01.pdf)
I’m looking for some advice to determine which filter to implement to ‘clean’ the received frequency. Does anyone have any ideas on how I could go about this? The received frequency will be in the GHz range I imagine due to the operating frequency being 24GHz.
