radar mechanism to monitor diy radar reflectors made on aluminum foils or tape or cd, any alternative to radar?

>To find a way to monitor trees in the forest.

That's really cool!

And I see you've chosen to use radar for your school project, so I assume it would be best for us to stick to that, as the idea is part of your project. Someone providing an alternative brilliant way would then be kind of like cheating.

I see you've figured out the idea of radar reflectors.

So the question that is left is: how do we build our own inexpensive radar?

Yes, that's what I was thinking too.

And I've done also some researching that's why I was asking for some opinions and suggestions on an inexpensive one but I was not able to deliver it much clearer.

Design goal, build a (better) radar reflector.

I suggest you limit your project to just the radar reflector design. Avoid any work that involves designing a radar. The scope of work to achieve just one of these goals is high, to accomplish both for a school project is setting yourself up for failure.

Before designing the reflector you do need to determine some method of testing your design. That means you need a source radar to use for testing and someone willing to assist in providing meaningful test results.

Using a ships radar might be effective. Ships radar can be portable and are easily available (at a cost). Do you have any means to access a ships radar? Do not limit your thought to purchasing one.

Those cheap modules are just used for close range detection of objects.

If you want to recognize boats at a distance it will take a pretty fancy radar, emitting fairly high levels of radiation and extensive signal processing of the return signal. Investigate commercial boat radars to get some idea of what is involved in a unit that can see a kayak.

It might be possible to use sonar instead.

Looks like a longer-distance radar would be rather complicated to build...

Good day Sir, I have reviewed the link you send.
It would be a cool idea to implement the design used on the video but I fear it would cost expensive for us, especially in our country here in the philippines where $1 is equals to 50php. so a $359 dollar design would cost around 16000php on our country and it would be very expensive for us but I appreciate the idea you gave on me.

anyway, im still searching for the past 2 weeks on what to do and what to use but I fear many questions are still coming in my mind when I search something but thank youuuu
