Principle and characteristics of radar speed measurement

1. Principle of radar speed measurement:

Radar speed measurement mainly uses the Doppler Effect principle: when the target is close to the radar antenna, the reflected signal frequency will be higher than the transmitter frequency; conversely, when the target is away from the antenna, the reflected signal frequency will be lower than Transmitter frequency. In this way, the relative speed of the target and the radar can be calculated by changing the value of the frequency. It has been widely used in industries such as police speeding test.

2. Features of radar speed measurement:

(1) When the vehicle enters the speed detection sign radar detection area (about 150m in the front of the logo), the microwave radar will automatically detect the speed of the vehicle and display it on the LED display to prompt the driver to pay attention to reduce the driving. Speed, which effectively reduces the occurrence of road traffic accidents caused by overspeed.

(2) The outer box adopts an integrated chassis, which has beautiful design and strong waterproof effect.

(3) There is a key switch hole on the back to facilitate inspection and maintenance of the product.

(4) Adopt super bright lamp beads, color matching, and clear colors.

(5) It is installed by hoop, which is easy to install and convenient.

(6) Powered by solar panels, energy saving and environmental protection, easy to use.
