Abstract
For a carrier wave carrying a microwave from an MW sensor, pulse intervals are varied between when the MW sensorgenerates an alert and when the MW sensordoes not generate an alert. When checking a sensing area, an operator carries a receiver being able to receive a transmitted wave from the MW sensor, walks around an area thought to be the sensing area and checks a monitor screen of the receiver. In this way, the sensing area can be checked at hand by the operator.
