Did you ever get a radar or lidar speeding ticket even through you weren't speeding, chances are the officer was not properly setup or misinterpreted the radar reading. The radar was not measuring you but a different vehicle or a false alarm. In many cases the radar was setup in a way it could not possibly measure your vehicle. Microwave radars measure the strongest vehicle reflection, not always the closest vehicle. Microwave radars have sensitive receivers, nearby transmitters and high power sources can induce false signals and false speed readings. Moving mode radar has multiple sources for incorrect speed readings that depends on traffic close to the radar and reflective stationary objects, like guardrails or highway signs. Lidars can produce a false reading if the target vehicle is greater than about 500 feet, the beam spread is wide enough to cause problems. At closer ranges the narrow beam must be aimed at the same vehicle surface or risk a speed error from 1 to 25 mph. Additionally lidars will produce a false speed reading by scanning the ground, no moving targets required. The Police Radar Handbook has the answers as to why you might have received that undeserved citation. The book explains proper radar and lidar use, and results of improper use. In many instances errors are predictable knowing just the general setup....

While many police departments effectively use radar to control traffic, there are still numerous instances of improper use. To operate traffic radar does not require genius, but it does require proper training as well as a basic understanding of this precision instrument. Unfortunately many people have the misperception that police radar is infallible, it is not. The "Police Traffic SPEED RADAR Handbook" is intended to familiarize the reader with the use and misuse of police radar by examining basic scientific and engineering principles in detail. There are numerous instances of unintentional (and a few intentional) abuses. Observing speed limits does not guarantee immunity from an undeserved ticket. Includes microwave and laser radar operation -- how radar works, proper use, limitations, potential operator errors, and common misreadings and mistakes. General situations are analyzed for potential, probable, and sometimes inevitable speed errors. In many instances errors are predictable knowing just the general setup. Basic radar theory, physics, and mathematics are used to prove all findings. All technical information and conclusions quantifiably described using illustrations, graphs, tables, or mathematical formulas -- based on or derived from fundamental scientific and engineering principles, published factory specifications, empirical data, or U.S. Government documents. Victims of microwave or laser police radar (or speed timing systems, pacing, visual estimate) as well as professionals involved with traffic law enforcement (Judges, attorneys, paralegals, police, prosecutors), accident reconstruction specialists, science and engineering professionals, educators and students will appreciate the detailed technical information and explanation....

The goal of this unique book is to give the reader a thorough understanding of speed enforcement concepts along with the devices that measure speed and, by means of interesting applications, to prepare them for their implementation in their professional careers. The text starts with a basis for the concept of speed in scientific terms and explores the concepts of speed as they relate to energy and work. The book also investigates both the negative and positive effects that various speeds have on travel and addresses the methodology to determining speed limits. Fundamental to the book are the devices used to measure speed. From the basic concepts of time distance determination through instant speed detection devices such as speed radars and speed lasers, the reader will explore the historical developments, scientific principles, and operational considerations of these devices. These sections are presented in depth with helpful charts and illustrations to assist understanding. The information is presented in easy to understand language to aid the reader in gaining a full grasp of both the scientific and operational differences of each technology along with the operative limitations associated with these technologies. Additionally, the book discusses the concept of voluntary speed compliance and the associated methods of achieving that. Further, the text reviews the elements needed for court scrutiny and acceptance of both speed law violations and the instruments used to measure those speeds and offers actual case examples that emphasize major legal points. The book is written with quantities and units in both U.S. and metric measure. This text is the most up-to-date and comprehensive resource concerning all methods used to monitor and enforce speed laws and is an ideal asset for traffic management courses....
