Wi-Fi 2.4-5 ghz is a decent radar spectrum… These are technically microwaves. Radar often uses radio waves. Where one ends exactly and the other begins is arguable. They are neighbors in the electromagnetic spectrum.
Depending on specific frequencies that you pick within their ranges you might be able to penetrate through certain objects, detect certain things based on absorption (water, bodies), etc.
