In a radar system, the basic set of components includes:
- Transmitter: Generates electromagnetic waves, usually in the microwave frequency range, and sends them through the antenna.
- Antenna: emits transmitted waves into space and collects reflected echoes from objects in the radar field of view.
- Receiver: Captures reflected signals from the antenna, amplifies them and converts them into a form suitable for further processing.
- Signal Processor: Analyzes received signals to extract information about the range, roll and speed of detected targets.
- Display System: Presents processed radar data in a human-readable format, such as a Plane Position Indicator (PPI) or radar plot, to help operators identify and track targets.
The basic components of radar on a ship are suitable for maritime applications:
- Radar antenna: positioned on a rotating mast or stabilized platform to scan the surrounding maritime and air space.
- Radar transceiver: combines the functions of transmitter and receiver into a single unit, managing the transmission and reception of radar signals.
- Display Unit: Provides a visual representation of radar data, displaying detected targets, navigation information and radar parameters.
- Control Panel: Allows operators to adjust radar parameters, such as range scale, sensitivity and display modes, to optimize performance for different operating conditions.
- Power Supply and Distribution: Ensures continuous operation of the radar system, with backup power sources available for redundancy at sea.
These components work together to provide critical assistance with situational awareness and navigation on vessels, detection of other vessels, obstacles and environmental conditions to improve safety and operational efficiency
