Technical Report: Ultrasonic Radar Security System Analysis

This report details the design and functionality of an ultrasonic radar security system, which utilizes ultrasonic sensors and a microcontroller to detect unauthorized objects within a specified range. The system employs a transmitter and receiver mounted on a rotating motor to monitor a 180-degree or 360-degree area, detecting changes in reflected energy patterns to identify objects. Upon detection, the system processes the data and alerts authorities, often using a buzzer or a liquid crystal display (LCD) to show object details. The report discusses the components of the system, including the microcontroller, open collector buffer, receiver, interrupt generator, and stepper motor, highlighting the software applications used for data transmission and display. The objective of the system is to measure distance and speed of detected objects, calculate the time interval between transmitted pulses and received echoes, and identify potential advancements in various sectors, making it a valuable tool for 24/7 monitoring and security.
