Working Principle
Transmitter: The transmitter generates a 240GHz signal using an oscillator. This signal is then amplified to a sufficient power level for transmission.
Antenna: The antenna system emits the radio waves into the environment in a controlled manner. The antenna’s design is crucial for achieving the desired beam shape and directionality.
Target Reflection: When the transmitted waves encounter an object, a portion of the signal is reflected back towards the radar.
Receiver: The receiver captures the reflected signal. It amplifies and processes the received signal to extract information about the object’s distance, speed, and direction.
Signal Processing: The received signal is processed to filter out noise and extract useful information. This includes techniques such as Doppler processing for detecting moving objects and range gating for determining the distance to the target.
Data Interpretation: The processed data is interpreted to extract meaningful information about the target, such as its size, shape, speed, and distance.
Applications: 240GHz radar transceivers are used in various applications such as automotive radar for collision avoidance systems, industrial sensing for level measurement and object detection, and security systems for perimeter surveillance.
