Traffic Radar for Motorists

The Radar Book/Manual is durable enough to last in your vehicle.  Each page is printed on heavy-duty, high-quality, smudge-proof paper using 4-color processing and high quality ink.  Radar information is summarized from over 3000 pages of police radar instructor's manuals.

We designed it so you can understand how radar really works!

We include graphics, diagrams and pictures to help you visualize each situation. Each story explains a different aspect of radar, independent of (yet building on) prior stories.  You'll understand how radar works as well as (or better than) the officers issuing the tickets. NHTSA Police Radar Training Manuals, both old and new are used.

We use over 20 true short stories (one page mostly, including cases that were dismissed) with different locations and terrain features to explain the basic functions of how radar works. We include nine different errors and their causes. We explain the proper use of radar, hints for the officer to prevent errors, and instructions to drivers in case you receive a false, erroneous ticket.  

The unique index provides a quick visual picture-guide to quickly find help.  We also include the Heads Up Display shown below, which will immediately help you spot trouble spots.

Hud 2 The invisible radar beam becomes visible!

This  "SUNBURST"  Heads Up Display is designed for training both officers and drivers. 

The projected image allows you to see where the radar beam is being transmitted and it's main beamwidth pattern.  Notice in this picture how the "Center Dot" and beam is aiming high towards the microwave tower on the horizon! What if you were car to the left? It even works at night! Test the HUD by clicking here.

At 1000 feet,  you'll see the 18 degree pattern of X-Band Radar which is over 300 feet wide.

You'll see the 12 degree K-Band Radar pattern, which is over 200 feet wide. 

Plus, you'll also be able to see the 3-4 foot width of the Laser, Lidar, or Ladar light beam. 

Vehicle size versus reflectivity is deceiving. The total reflectivity of any vehicle is the 3-part-sum of its reflective parts.   1. The glass windshield will refract radar (passes it through) while 2. plastic and fiberglass hoods and fenders absorb (retain) radar. 3. The amount of metal to reflect (bounce) back to the police radar unit varies with each vehicle type.  Even dirt changes the reflectivity of vehicles for laser. This is why a vehicle overtaking you (a larger Sport Utility Vehicle - SUV or 350 Pickup Truck) can reflect a stronger signal back to the radar than your mid-size, all fiberglass sports car.

Since radar starts recording high at 256 MPH and scans downward, it will report a higher speed of the vehicle coming up from behind you even though you are closer. A higher speed is received and reported by the radar unit more quickly, with your slower speed ignored. You may be wrongly targeted and issued the ticket.

This visual display helps explain why you got the ticket that should have gone to another driver!  Wrong Target!

There are many rules for operating radar including properly set speed zones, training, equipment requirements, and need for operation in high accident locations or problem areas.  We provide you with  "auditor's information" so you can ensure quality, not quantity.  

Speeding tickets must be issued to the correct driver.  There is no room for error! When in Doubt, DO NOT Issue! is the rule for officers.
