This article discusses a simple ultrasonic sound sensor alarm circuit which may be appropriately set for detecting sound pressures well above the normal human listening capacity, that may range from 20 kHz and over.
The post explains a GHz microwave radar security alarm circuit which is designed to detect an intruder within the critical zone only while it's moving, static objects produce no effect for the sensor.
