Easy to understand and fully illustrated description of everything every driver, and the police, should know about traffic speed radar. Police radars are not just point (at target) and click (transmit) devices. There are some basic setup limitations and operating procedures that must be observed. Too often procedures are not properly followed in order to save a little time or hide from motorists, resulting in speed errors. This book details radar types and operating modes, proper use and test (including the widely misunderstood tuning fork test), limitations, calibration records, and how Doppler radar works. Anyone that operates a police radar should already understand everything presented. However, far too many operators don't remember or don't use what they were taught in radar training.

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.

The purpose of this study was to examine two instructional methods for delivering a radar operators training class for members of a municipal police department. The first method examined was the traditional classroom-based training with a certified radar instructor. The second method was a computer-based training (CBT) course based on the instructional material from the classroom-based course. The CBT course was administered on CD-ROM using the police department s Windows(c) based computers. This study compared the two methods of delivery to determine if the CBT course was as effective as the traditional classroom-based course. Effectiveness was measured by the completion times of the two courses, examination scores, and overall participant satisfaction levels. These measures were conducted using quasi-experimental design that involved two sample groups. The total population was sixty-nine police officers. The sample contained fourteen participants, divided into two equal groups of seven. The independent variable was the instructional method. The dependent variables were the course completion times, examination scores, and the satisfaction levels of the participants. Of the two groups of police officers, Group 1 received the CBT for radar operators, while Group 2 received the traditional classroom training. Data was gathered regarding the completion times, test results, and participant satisfaction levels of the two courses. A statistical analysis of the data was conducted to determine the difference in course completion times, test scores, and participant satisfaction levels between the two courses.
