1. In past few years the technology and applications of RADAR have continued to grow.

2. There has been extensive advances in the use of Digital technology for signal processing, significant improvements in the use of infrared for detecting moving targets in heavy clutter.

3. Taking forward this new trend we plan to design and develop a RADAR system for catering personal needs

PROBLEM STATEMENT

3

1. We plan to design a type of close proximity infrared radar system used to detect any object close to the device by making scanning with angle 180°and distance from 10cm to 500cm.

2. The system is based on microcontroller design. The user will hear a voice just as alarm sound and the distance of the object will be readable on the screen of small LCD.

3. The user also can see the light given by LED appear in the direction of the object.

• A shorter frequency-modulated pulse can be transmitted alternately. This method is typically for collision avoidance radars, which doesn't need a special characteristic in the minimal measuring range. 

• The shorter pulse is an un-modulated very short pulse ( <1 µs). The limited pulse power causes a shorter maximum range in this period. This method is typically for traffic-control radars (ATC-radars), like the ASR-E). 

• The needed pulse power is dynamically balanced in dependence on the chosen elevation angle. The pulse duration determines the maximum range therefore.

WHY SHORT RANGE?

PAPER TITLE :Design Infrared Radar SystemAUTHOR :Yahya S.H. KhraisatDescription :The paper describes about interface of controller and motor with sensor.The stepper motor will be turned on with instruction to rotate 180 by PIC. The stepper motor will drive the IR SENSOR this sensor consist of emitter and detector. The emitter will send an infrared signal to detect an object. When this signal hits the object, the signal will be reflected back to the detector. Then the detector will send analog signal with suitable voltage and angle. The voltage of this signal is suitable with the distance. The controller will make its and convert analog signal to digital by A/D and give a command to the led which indicate in the direction of the object.

PAPER TITLE : Short Range Radar Based on UWB Technology AUTHOR : L. Sakkila, C. Tatkeu, Y. ElHillali, A. Rivenq,

ElBahhar and J-M. Rouvaen. Description :Radar sends very short electromagnetic pulses. This type of radar can employ traditional UWB waveforms such as Gaussian or monocycle pulses. To calculate the distance between radar and obstacle, the time delay Δt between emission and reception is measured.

This distance is given by:

where c is the light speed. This radar offers a resolution in distance of about 15 cm for a width pulse of 1ns, so that this system is very interesting for short range road safety applications.

• RADAR in simple language is the contraction of words

“Radio Detection and Ranging”.

• RADAR is a device which works on radio frequencies

that use microwave source of energy to detect and to

calculate the range of the target.

Conclusion and Summary

18

Radar is briefly defined as method of using radio wave to determine the location of objects in space in relation to a known point.

More precise definition of radar is that it is an electromagnetic system for detection, location and sometimes for recognition of target objects, which operates by transmitting electromagnetic signals, receiving echoes from target objects within its volume of coverage, and extracting location and other information from the echo signals.

IR Radar is an application of automotive radar, where this type of pulse radar is operating by sending short pulse to make scanning.

The goal of this project is to create a working IR Radar system to DETECT close proximity targets in its RANGE.
