  A radar speed gun is an electronic device utilized to read the velocity of moving objects at a specific interval. It's the most frequently utilized in law enforcement to monitor the speed of certain moving vehicles and has also been utilized in professional sports for matters relating to the measurement of cricket speeds in cricket, tennis, and golf. The device emits a radio wave that's in constant radio frequency with the object being measured. Radiofrequency is the wavelength of electromagnetic radiation emitted by various electric or electronic devices. The measurement is done by measuring the amount of time the radio wave has taken to travel the distance the device is from the object it's measuring. When using radar equipment for law enforcement, the radar gun must be calibrated and certified by the local law enforcement agency that uses the technology. This ensures that each individual radar speed gun can work properly and report accurately the speeds of arriving ...

  Automotive radars are usually used to detect the velocity and distance of vehicles in the surrounding area. An automotive radar normally consists of a receiver and transmitter. The transmitter sends radio waves out into the area, and the receiver reflects them back to the transmitter, identifying the distance, speed and direction of the reflected signals. The demand for automotive radars is expected to decline in major markets of Europe such as the U.K and Germany. This is attributed to decline in sales of automobiles. According to the Society of Motor Manufacturers and Traders, the new car registrations in the U.K. decreased by 44% in March 2020 compared that in March 2019. Automotive radar is designed to operate in a silent mode. However, when they are activated by a person's movement, the systems produce audible and sometimes annoying noises. Manufacturers are now focused on 4D imaging radar. Israel-based start-up Vayyar recently reported development of a 4D imaging radar,...
