The braking distance at 40 mph is not twice the distance require at 20 mph but 4 times. Further the braking distance at 80 mph would not be 4 times the distance required at 20 mph but more than _____ times - Correct Answer- Braking distance: 4x is - Correct Answer-40mph Braking distance: 40mph is - Correct Answer-4x Braking distance: 80mph is - Correct Answer-16 Braking distance: 16x is - Correct Answer-80mph Reaction time of a normal person is - Correct Answer-.75 seconds Which speed law has the following elements. Reasonable, prudent under existing conditions? - Correct Answer-Basic Which speed law loosely translated means at first site/glace, a fat presumed to be true unless disapproved buy some evidence to the contrary - Correct Answer-Prima facia Relative motion is best described as - Correct Answer-The object stand still and the radar moves, the radar moves and the object stand still, the radar and the object are moving in the same direction at different speeds The only time a radar will show you the true speed of a vehicle is if - Correct Answer- The vehicle is going directly toward or direct.y away from the radar In stationary mode the angle/cosine effect is always going to show a higher than true target speed - Correct Answer-False Never set the radar up any further than _____ degrees from the target vehicles direction of travel - Correct Answer-20 The radar point of aim does not have an impact on the magnitude of the angular effect - Correct Answer-False In moving mode your radar determines what two things? your speed relative to the _____ and the target vehicle relative to the _____ - Correct Answer-Target vehicle, the ground In opposite direction you will always have a closing or separation speed faster or slower than your patrol speed - Correct Answer-Faster The reflected signal from the target vehicle has undergone a _____ Doppler shift, the signal from the patrol car to the ground has undergone a _____ Doppler shit - Correct Answer-Hi, low If you are operating in moving opposite direction front antenna what formula will you use - Correct Answer-TS=CS - PS If you are operating in moving opposite direction rear antenna what formula - Correct Answer-TP=SS - PS If you are operating in moving opposite direction and your patrol speed at 65 mph and the target speed is 75 mph what is the closing or separation speed - Correct Answer- 140 The best way to illuminate target selectivity issues is to rely on your own ability to - Correct Answer-Estimate vehicle speed When you are clocking a car and suddenly the clock goes away for a time Then reappears could be an example of - Correct Answer-Multi path beam cancellation Neon lights, CB radios, high power lines are examples of - Correct Answer-Man made interferences If making a clock in stationary mode, you move forward or backwards during the clock this is an example of - Correct Answer-Scanning If you have a two piece radar and while pointing the antenna at the counting box you receive a strange reading, this could be an example of - Correct Answer-Panning In moving radar you have ____ beams transmitted and _____ reflected back - Correct Answer-1,2 In moving radar operation we always want to set the antenna as close as possible to - Correct Answer-0 degrees When you are receiving your patrol car speed of the vehicle in front of you instead of the road and roadside objects this is example of - Correct Answer-Shadowing If you rapidly accelerate or decelerate while making a clock what type of effect is this - Correct Answer-Batching In moving radar batching, shadowing, double bouncing an angle effect can give you a - Correct Answer-Higher than true target speed Same direction radar may not process speeds from _____ to _____ MPH up or down from the patrol car speed - Correct Answer-3-6 Moving same direction radar uses the same fundamental principles as all other types of speed measuring radar.
