Abstract
A communication device can be configured to detect radar signals within an operating channel. The communication device can include a mixer, filter, scanning and spreading circuit and a radar signal detector. The mixer can be configured to modulate a received communication signal based on an oscillating signal to generate a modulated signal. The filter can have a first bandwidth and be configured to filter the modulated signal. The scanning and spreading circuit can be configured to control the oscillating signal to scan an operating channel having a second bandwidth. The second bandwidth can be greater than the first bandwidth. The radar signal detector can be configured to detect a radar signal within the scanned operating channel.
