Radar signal processing is the critical step in converting the raw signals received by the radar receiver into usable data. This involves filtering, amplifying, and analyzing the signals to detect targets, calculate their speed, and generate radar images. Advanced signal processing techniques, such as Fourier transforms and pulse compression, are used to improve the resolution […]

The new SharpEye S Band Radar by Kelvin Hughes features solid-state technology, offering superior target detection and reduced maintenance. It is designed for enhanced performance in maritime surveillance.
The radar receiver is responsible for receiving the reflected radar signals from objects in the radar’s path. These signals are then processed to extract useful data such as distance, speed, and direction of the target. The sensitivity and frequency range of the receiver are crucial for the radar system’s ability to detect even weak signals […]
Surveillance radar is used for monitoring large areas and detecting moving targets, such as vehicles, aircraft, and ships. It is widely used for security, border protection, and in military applications for detecting potential threats. Surveillance radar systems can provide continuous monitoring, even in adverse weather conditions or low visibility, making them indispensable for maintaining safety […]
Military radar is a critical element of modern defense systems, used for detecting and tracking enemy aircraft, missiles, and ships. These radar systems can operate over long ranges and provide real-time data for surveillance and targeting. Military radar often uses advanced technologies like phased array antennas, pulse Doppler, and synthetic aperture radar (SAR) to achieve […]
Ground Penetrating Radar (GPR) is a non-invasive radar system used to image the subsurface of the Earth. It transmits high-frequency radio waves into the ground, and the reflected signals are analyzed to detect structures, objects, or variations in soil composition. GPR is widely used in archaeology, geology, environmental studies, and construction, helping to locate pipes, […]
Frequency Modulated Continuous Wave (FMCW) radar is a type of radar that uses frequency modulation to measure the distance to a target and its velocity. The radar emits a continuously modulated signal, and by comparing the frequency of the reflected signal with the transmitted signal, the radar can determine both range and speed. FMCW radar […]
Continuous Wave (CW) radar operates by continuously transmitting a signal and measuring the Doppler shift of the reflected signal to determine the speed of a moving object. Unlike pulse radar, which transmits discrete pulses, CW radar continuously emits waves, making it ideal for speed detection and tracking moving targets. CW radar is often used in […]
Phased Array Radar is a type of radar system that uses multiple antennas arranged in an array to electronically steer the radar beam without physically moving the antenna. This allows for faster scanning and improved accuracy in detecting and tracking targets. Phased array radar is commonly used in military applications, air traffic control, and marine […]
Synthetic Aperture Radar (SAR) is a powerful radar system that uses the motion of the radar platform (typically a satellite or aircraft) to simulate a much larger antenna, enhancing image resolution. By capturing detailed images of the Earth’s surface, SAR is commonly used for environmental monitoring, topographic mapping, and oceanography. Its ability to produce high-resolution […]
