Assignment#1 Survey on sensors and actuators Scott JenkinsSlide-6Basic Working Principles of millimeter wave radar•Millimeter wave radar first began to be developed during the 1950’s at what is now Georgia Tech Research Institute GTRI. This expanded the envelope of radar technology at that time.01/15/19ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators Scott JenkinsSlide-7•One of the basic principle behind radar is the ability to transmit and receive electromagnetic energy.01/15/19ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators Scott JenkinsSlide-8•One of the basic principle behind radar is the ability to transmit and receive electromagnetic energy.•Another important principle is the reflection of electromagnetic energy by objects and surfaces01/15/19ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators Scott JenkinsSlide-9•The radar signal is transmitted and directed by an antennahttp://ww2010.atmos.uiuc.edu/(Gl)/guides/rs/rad/basics/sgnl.rxml01/15/19ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators Scott JenkinsSlide-10•This transmitted signal is scattered by distant objects. Part of this scattered signal is reflected back at the radar transmitter and is captured by a receiving antennahttp://ww2010.atmos.uiuc.edu/(Gl)/guides/rs/rad/basics/sgnl.rxml01/15/19ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators Scott JenkinsSlide-11•The way that the signal reflects off of an object has a lot to do with the wavelength of the radio wave transmitted by the radar equipment. If the wavelength is much smaller than the object than the signal will be scattered in much the same way as light is reflected off an object.01/15/19ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators Scott JenkinsSlide-12•As indicated by the electromagnetic spectrum light waves have wavelengths on the order of a micrometer, while radar about three orders of magnitude greater in wavelength.http://www.equiworld.net/uk/horsecare/alternativetherapies/lighttherapy/01/15/19ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators Scott JenkinsSlide-13•Because the wavelength of light is much smaller than macroscopic objects, high image resolution of the object that the light reflected off is possible.01/15/19ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators Scott JenkinsSlide-14•Because the wavelength of light is much smaller than macroscopic objects, high image resolution of the object that the light reflected off is possible.•This concept is the basis for research and applications of millimeter wave radar.01/15/19ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators Scott JenkinsSlide-15•Because the wavelength of light is much smaller than macroscopic objects, high image resolution of the object that the light reflected off is possible.•This concept is the basis for research and applications of millimeter wave radar.•The idea is to increase resolution of the object reflecting the radar signal by decreasing the radar wavelength as much as possible.01/15/19ECE5320 Mechatronics.
