Abstract:
RADAR is an object detection system which uses radio waves to determine the range,
altitude, direction, or speed of objects. The radar dish or antenna transmits pulses of
radio waves or microwaves which bounce off any object in their path. Arduino is a
single-board microcontroller to make using electronics in multidisciplinary projects
more accessible. This project aims at making a RADAR that is efficient, cheaper and
reflects all the possible techniques that a radar consists of.
The proposed system "ultrasonic radar for the object detection distance and the
speed measurement” employs an ultrasonic module that includes an ultrasonic
transmitter and receiver. It operated by transmitting 40 kHz frequency pulse which is
not audible to the human ear.
Module rotate with step angle of the stepper motor with specific angle for a specific
time interval and the distance between the object and system is measured by calculating
time interval taken by the signal to transmit and the echo reception Whereas the detected
signal is shifted toward the module or away from the module which give the information
about the speed of that detected object which is shown on PPI DISPLAY
Description:
RADAR is an object detection system which uses radio waves to determine the range,
altitude, direction, or speed of objects. Radar systems come in a variety of sizes and
have different performance specifications. Some radar systems are used for air-traffic
control at airports and others are used for long range surveillance and early-warning
systems. A radar system is the heart of a missile guidance system. Small portable radar
systems that can be maintained and operated by one person are available as well as
systems that occupy several large rooms.
