Systems and methods for self-adjusting a monitoring pattern range of a microwave sensing device

Abstract

Some systems for self-adjusting a monitoring pattern range of a microwave sensing device can include a microcontroller coupled to the microwave sensing device, an antenna of the microwave sensing device, signal processing circuitry of the microwave sensing device coupled to the antenna, and a digital potentiometer of the microwave sensing device coupled to the signal processing circuitry. The antenna can detect an object and transmit an object detection signal to the signal processing circuitry for processing thereof, and the microprocessor can sample a processed microwave intermediate frequency signal output from the signal processing circuitry, determine a monitoring pattern range of the microwave sensing device responsive thereto, and transmit an adjustment signal to the digital potentiometer to adjust a gain of a microwave intermediate frequency of the signal processing circuitry to adjust the monitoring pattern range by increasing or decreasing a detection sensitivity level of the microwave sensing device.
