Introduction

Speed radar and laser guns are primarily used in law enforcement to detect the speed of a passing vehicle. With the introduction of video recording systems in police vehicles it has been natural requirement to interface the speed gun with the video system. This will produce an indisputable video recording of the actual vehicle along with the speed of the vehicle overlayed in the video
simultaneously. Review in court or reviewed at the scene, lends itself to higher prosecution rates therefore high revenues ....etc

RANGING & LANDING SYSTEMS


The VHF Omni-directional Radio Range is the abbreviations for which are VOR and Omni , enables a pilot to determine the direction of his aircraft from any position to or from a VOR beacon

range

VOR is a Very High Frequency (VHF) navigation aid which operates, its ground to air range is limited to line of sight reception which is typical of VHF transmission. The range achieved is dependent, therefore, on the siting of the VOR beacon with relat ....etc

We come across situations where we need to keep a watch over prohibited areas to avoid trespassing. Now keeping human labour for this purpose is costly and also not reliable for keeping a watch over an area 24 7. So for this purpose an ultrasonic radar project for unauthorized human / animal or object detection system. The system can monitor an area of limited range and alerts authorities with a buzzer as an alarm. For this purpose we use a microcontroller circuit that is connected to an ultrasonic sensor mounted on a servo motor for monitorin ....etc

This paper will demonstrate how maglev trains work with electromagnets. We will provide information about the history of early electromagnets. We will also provide information on the locomotion process, which is done through the generation of an electromagnet field by the rotor around the stationary magnet causing the torque from the magnet to pull or push it . The paper will describe how each part of the electromagnet works. There are projects that we will discuss that helped further the development of electromagnets. We ll inform the read ....etc

RADAR Radio Detection And Ranging

Radio Detection And Ranging ,in short RADAR relies on sending and receiving electromagnetic radiation, usually in the form of radio waves (see Radio) or microwaves. Electromagnetic radiation is energy that moves in waves at or near the speed of light. The characteristics of electromagnetic waves depend on their wavelength. Gamma rays and X rays have very short wavelengths.

Visible light is a tiny slice of the electromagnetic spectrum with wavelengths longer than X rays, but shorter ....etc

What is lidar???
Light detection and ranging(LIDAR) is an optical Remote Sensing Technology that can measure the distance to an object or surface.

It is similar to Radar, but it incorporates laser pulses rather than radio waves.

Stereoscopic Passive Millimeter-Wave Imaging and Ranging

Thomas L thi and Christian M tzler, Senior Member, IEE


Abstract

This paper presents the first stereoscopic range measurements
at a wavelength of 3.3 mmand discusses the accuracy of
this new method. The synthesis of passive millimeter-wave imaging
and stereoscopy combines the advantages of both principles, naturally
looking high-contrast images and superior poor-weather performance
(compared to visible and infrared wavelengths), as well
as the pas ....etc

ABSTRACT

Light Detection and Ranging (LIDAR) have recently become the technologies of choice in mass production of Digital Elevation Models (DEMs), Digital Terrain Models (DTMs), and Triangulated Irregular Networks (TINs), referred to generically hereafter as DEMs. This paper presents lessons learned from LIDAR projects to date in various states. It addresses opportunities presented by LIDAR for generating DEMs as articulated by various user groups in the National Height Modernization Study. Finally, it summarizes actions required by th ....etc
