1) What is Constant ON?
This is a mode of operation where the radar signals are constantly transmitted from a radar unit that is used by the law enforcement.
Most Radar detectors are able to easily detect this signal as the radar unit is emitting the signal constantly in this operating mode.
2) What is Instant ON?
In this mode, the radar transmitter unit is kept in a standby mode where it is not transmitting any signal. The law enforcement officer identifies his target and pulls the trigger to transmit short bursts of radar waves. By using this method, the speed of the target can be identified as quick as 0.16 second. This is faster than the time needed for a radar detector to detect the signal and raise an alert.
Practically if you were the target to be aimed at your radar detector will not be of much help. However, if aimed at a car that is ahead of you then the radar detector will be able to detect this signal and alert.
3) What is a Radar Detector Detector (RDD)?
RDD’s are devices used by law enforcement to detect the use of radar detectors. Devices such as the VG-2 Interceptor, Spectre I, Spectre Mk IV etc. are used in places where the use to radar detector is illegal to detect such use.
Radar detectors can legally be used in 49 states across the U.S. Only Virginia and Washington DC have outlawed the use of radar detectors. Most provinces in Canada also do not permit radar detects to be used. Since 1995, radar detectors cannot be used on any commercial vehicle.
4) What is POP mode?
POP Mode refers to a patent pending technology from MPH industries that manufactures police radar. It allows the operator to measure the speed of potential violators in stationary mode without setting off a single radar detector.
In this mode, the radar device can transmit radar waves in short burst and read a target speed in less than 3/10th of a second. This is very quick for a radar detector to detect the signal and the net result is that there is no alert from the radar detector.
5) What is LIDAR?
LIDAR is the acronym for Light Detection and Ranging. It is a common method of speed detection by means of pulsed infrared light also known as LASER, gradually replacing the use of radar.
A typical LIDAR device emits pulses of laser light with a wavelength of 905 nanometer. The time interval between pulses is no less than one million nanosecond, providing time to make a distance estimation from each pulse. Up to several hundred pulse readings are taken over a period less than half a second and used to estimate the change in distance over time, thereby estimating vehicle speed.
6) Is Digital Signal Processing Important?
Digital Signal Processing or DSP is a subfield of signal processing and the other being analog processing. A DSP circuit is able to differentiate between human-made signals which are orderly and noise which is inherently chaotic. The main advantage of DSP over analog is that it provides more accurate, efficient and reliable signal processing.
In the field of radar detection, DSP chips are used to identify the radar signals quickly and more efficiently. Hence, they are able to provide warning/alert much quicker than a detector using an analog system. Also, the DSP chips use accurate and efficient algorithms to filter false signals or noise. This will improve the performance of a radar detector in terms of identifying the right radar signal and filtering out the unnecessary ones.
A good radar detector should be able to identify the right signal, filter out the wrong ones and alert the user quickly. In a real-world scenario where every second could make a difference between getting a ticket issued or not a radar detector using this technology is definitely an added advantage.
7) What does Wideband and Superwide Ka mean?
The use of Ka band in law enforcement came into existence with the introduction of Photo Radar which operated at 34.3 GHz. Radar detector manufacturers added Ka-band monitoring. After these manufacturers of radar gun introduced devices that operated between 34.2 GHz and 35.2 GHz. Again, radar detector manufacturers had to monitor this frequency range and called it Wideband Ka.
At a later stage, Federal Communications Commission permitted the use of 35.5 GHz to be used for traffic speed monitoring and radar gun manufacturers introduced devices that operated at 35.5 GHz. Hence radar detector manufacturers had to monitor the frequency from 33.4 GHz to 36.0 GHz and called it Superwide Ka.
