24 GHz Proximity Sensor
Bruce Unger and Chad Campen
Advisor: Dr. S.N. Prasad

In today's society, the need for new products to increase the safety of the individuals is apparent. Several products are now being developed in the wireless communication industry for this purpose. The 24 GHz Proximity Sensor utilizes radar technology to determine and display the range of a stationary object with respect to the radar. This project can affect the world directly, especially in the automotive industry. As a result of mounting the system on the rear bumper of an automobile, the range of stationary objects behind the vehicle will be provided to the driver of the car.
This project is designed around the Northrop Grumman TR1G946 monolithic microwave integrated circuit(MMIC) transceiver chip. Objectives include background research of radar technology, characterization of the transceiver chip, and the system design to extract the range information. Utilizing multiple frequency continuous wave radar, the intermediate frequency output of the transceiver chip is a square wave. The amplitude of the square wave is proportional to the desired range, which can then be displayed to the driver of the automobile.
