What you describe sounds like a home-brew radar. Transmit a brief burst, then turn it off, then go into listening mode.

There are transistors known as 'microwave' transistors which are made to operate at rf frequencies. Build a tunable oscillator around it.

Or, you might start with a commercial unit on your band of frequencies. Alter it so you can adjust it. Wi-fi module, wireless network module, hand-held phone, etc.
