How many types of radar systems are there?
There are several types of radar systems, each designed for specific applications and operational environments. Some common types include:
Primary radar: Also known as surveillance radar, this type detects the presence and position of objects by measuring the delay and Doppler shift of radio waves reflected from the target.
Secondary Radar: Often used in conjunction with primary radar, secondary radar systems involve transponders on board targets that respond to interrogations from the radar, providing additional information such as identification, altitude and speed.
Weather Radar: Specially designed to detect precipitation and weather phenomena, weather radar systems operate in optimal frequency bands to detect water droplets and ice crystals in the atmosphere.
Synthetic Aperture Radar (SAR): SAR systems use advanced signal processing techniques and the movement of the radar antenna to create high-resolution images of the Earth’s surface, even in adverse weather conditions or the night.
Phased Array Radar: Unlike traditional radar with a mechanical rotating antenna, phased array radar uses electronic ear antenna arrays, allowing rapid scanning and precise beam control.
Airborne Radar: Installed on aircraft, airborne radar systems are used for navigation, weather avoidance, ground mapping and target detection.
Marine Radar: Used for navigation and collision avoidance at sea, marine radar systems detect nearby ships, coastlines and other obstacles in varying weather conditions.

The three main parts of a radar system are:
Transmitter: Generates electromagnetic waves, usually in the form of short pulses, and sends them through the radar antenna.

Antenna: Emits radar pulses into space and collects reflected signals from objects within its range.
Receiver: Receives and processes reflected radar signals that are returned from objects within the radar coverage area. The receiver amplifies, filters and analyzes these signals to extract information about the range, speed and other characteristics of the detected targets.
