80GHZ Radar Manufacturers Use Innovative Technologies To Improve Radar Performance And Production Efficiency

The 80GHZ millimeter wave radar system consists of multiple important components, including antennas, radio frequency front-end components, digital signal processors and radar control circuits.

In the radio frequency front-end component of the 80GHZ ranging radar system, it is mainly responsible for the modulation, transmission, reception and demodulation of echo signals of millimeter wave signals. The current mainstream RF front-end integration method for 80GHZ radar manufactures uses monolithic microwave integrated circuits (MMIC). This method has the characteristics of high integration, low cost, and high yield, and is more suitable for mass production.

The digital signal processor is one of the core parts of the 80G radar level gauge manufacturer system. By embedding different signal processing algorithms, digital signal processors are able to extract signals from the front end and obtain specific types of target information. The digital processing algorithms of 80GHZ radar manufactures include array antenna wave speed formation and scanning algorithms, signal pre-conditioning, clutter processing algorithms, target detection/measurement algorithms, target classification and tracking algorithms, and information fusion algorithms, etc.

The antenna is an important part of the 80GHZ millimeter wave radar system, which can transmit and receive millimeter wave signals. The antenna is small and usually integrated on the PCB board. According to the antenna mode, it can be divided into long-range radar (opening about 30°, 200m), medium-range radar (opening about 60°, 100m) and short-range radar (opening about 120°, 30m). ).

The control circuit is an important part of the 80GHZ radar manufactures system. It can perform data fusion based on the target information obtained by the signal processor, combined with the dynamic information of the radar terminal, and finally perform intelligent processing through the main processor to detect obstacles appearing in front of the radar terminal. Analyze and judge, quickly process and issue instructions, and promptly transmit them to the alarm display system and brake execution system, thereby achieving effective control and management of the radar terminal.
