I am determined to build a radar detector, not necessarily because I don't want to buy one, but more or less as a fun science project. I have tried to do some research on the internet about how radar detectors are made, but my search has yielded few results. From what I understand, a superheterodyne receiver is used to pick up frequencies being broadcasted on the X and K bands, but that is about all I can find. I can't seem to find how the detectors are put together and what parts I need. Can anyone point me in the right direction? Just a simple schematic or something to help me get started. Thanks guys!
