What is the function of the scanner in the radar?
The function of the scanner in radar is to direct the radar beam or antenna to different directions in order to scan the surrounding environment for targets or objects of interest. The scanner allows the radar system to systematically cover a specific area or volume of space, enabling the detection, tracking and surveillance of targets such as aircraft, ships, weather phenomena and other objects.
Depending on the radar type and application, scanners can be mechanical (rotating or movable antennas) or electronic (phased array antennas or electronically refined arrays).
By scanning, radar systems can collect information about the location, distance, direction, speed and other characteristics of targets within their operational range.
Radar systems consist of several key parts, each serving specific functions to enable the system to effectively detect, track and process radar signals:
the function of the scanner in the radar
Antenna: The antenna transmits radar pulses into space and receives reflected echoes from targets.
It focuses the transmitted energy into a beam and collects the received signals for processing.
Transmitter: The transmitter generates the high frequency electromagnetic signals (microwave pulses) that the radar antenna transmits into space. It provides the power needed to produce the radar pulse and controls the pulse characteristics.
Receiver: The receiver amplifies and processes weak radar echoes received by the antenna.
It extracts and analyzes information embedded in received signals, such as target position, speed and characteristics.
Duplexer: The duplexer is a switching device that alternates the radar system between transmit and receive modes. It ensures that the sensitive receiver is protected from high power transmitter pulses.
Signal processor: The signal processor processes the received radar signals to extract useful information about detected targets.
It applies algorithms for target detection, tracking and data analysis, converting raw radar data into actionable information for operators.
Display System: The display system presents processed radar data in a format that can be easily interpreted by radar operators.
It may include radar displays, digital displays, or integrated systems that provide real-time situational awareness and visualization of radar information.

Control System: The control system manages and coordinates the operation of various radar components, including the scanner, transmitter, receiver and signal processor.
It allows operators to adjust radar parameters, such as scan patterns, frequency and power settings, to optimize performance for different operational scenarios.
Each part of the radar system plays a crucial role in its overall function, from transmitting radar signals and receiving echoes to processing and presenting information about detected targets.
Together, these components enable radar systems to fulfill their roles in military defense, air traffic control, weather monitoring, navigation aids, and various other applications where precise object detection and tracking is essential.
