2. INTRODUCTION
With the rapid development of economy, the number of cars
has increased greatly. In order to avoid traffic accidents, it is
important to improve the safety and reliabilityof automobiles.
Automotive radar is avehicle assistant driving system that can
prevent accidents. There are many types of automotive
radar.
Collision avoidance radar
Parking assistance radar
blind spot detecting radar
3. RADAR V/S SENSOR
Radar is a remote sensing and detection technology that used
radio waves to locate targets, their angle and velocity where as
sensor is a range imaging camera technology that used infrared
light to determine depth information.
4. SENSOR LIMITATION
• The required line of sight
• Limited range, support a shorter range
• Can be affected by environmental conditions such as rain, fog,
dust, pollution, sunlight, smoke, etc
• Some time gets false result.
7. SHORT RANGE OF RADAR
1. 15 cm – 30 cm range
2. Frequency range 24 GHZ
3. 9dBm/HZ transmit power used
4. Ex: Blind spot detection
parking assistant
collision avoidance
8. WHY AUTOMATIVE COLLISION AVOIDANCE RADAR?
Enhanced Vehicle Security is the need of the Modern
Automative Industry.
Need to detect a vehicle at a critical speed and at a critical
distance.
Most recent Standard of ETSI EN 302 288-1 V1.1.1 (2005-
01 ) defined in Jan 2005: Band of 22- 26.625 GHz is most
suitable for Automobile collision avoidance Radars.
9. BASIC REQUIREMENTS OF AN
AUTOMOBILE RADAR
Low Side lobe Level
Higher Directivity.
Higher gain.
Low Return Loss.
10. SOFTWARE REQUIREMENTS
CST Studio
ADS (Advance design system )
Qucs software
Computer Aided Design(CAD)
11. FUTURE WORK
Design collision avoidance radar.
Make it a Electronically Scanned Array.
Reduce the Side lobes using different type of
distribution(Chebyshev distribution, active distribution) in
feeding line.
Trying out different feeding lines like Comb line feed and
measure its performance.
Decrease the size of radar as much as possible.
Also design other short range radar (which is working at range
22Ghz to 26Ghz).
12. MY DESIGN
I have design antenna array for air surveillance
radar in LRDE Bangalore
I study and practically design the research paper
“Millimeter Wave Microstrip Antenna Array for
Automotive Collision Avoidance Radar” Yu Zhang,
