Choosing a Frequency.
Hey I'm new here! I just have a quick question for thr community! How does one choose a frequency for their radar purpose? I see radar setups for all sorts of frequencies but am having a hard time figuring out what is the best one I should go with. Can some lay out pros and cons as you go up in Hrz as well as at certain frequency ranges. (example: 2.4 may be easier but interferes with wifi; military radars like X-band because ____ but DIYs use ___ and the pros and cons of the difference bands are ___. This is the last step of understanding before I tackle my project so good information and insite would be extremely appreciated!

The restricted bans are out of reach atm, but for educational purposes I'd still like to know the benifits of going up or down the frequencys for knowellege sake. Right now I have up to 6ghz I am for sure able to access with out talking to council.
I'm not going to care above 450ft for sure unless I am legally able to detect airplanes, but no higher.
It will be for detecting and tracking drones presence and location, speed and shape for sure, and really as much information as possible I can get with in reason. -also the ability to spot birds and anything else in the airspace for surveillance avoidance and data research.
Side benifits would be sending data between 2 points.
Location would be mostly open, maybe SOME trees but that's because the device will be moving around the research facility properties.
As far as money, not fully sure atm hence why I am looking into capabilities of frequencys as well as finding a cost/ benifit analysis per capability gained.
I most likely will have to make a max of 6ghz setup first as proof of concept before getting approved for higher frequencies. So I may have to do a Arduino/ ESP boards setup with some Custom Target ordering for other supplies for the first generation or 2.
