What kind of modulation is commonly used in modern RADAR systems?

In modern RADAR systems, phase coding is often utilized due to its advantages in improving the detection and resolution of targets. Phase coding involves varying the phase of the transmitted signal, which allows for better discrimination of targets in cluttered environments. This technique enhances the ability to separate signals from multiple sources and provides improved immunity to interference, making it particularly effective for modern applications where precision is crucial.

This approach is beneficial in different RADAR modes, including synthetic aperture RADAR (SAR) and pulse-Doppler RADAR, allowing for efficient data processing and analysis. Phase coding also facilitates advanced signal processing techniques that contribute to enhanced target detection and tracking capabilities. As technology progresses, the need for higher accuracy and reliability in RADAR systems continues to push the adoption of phase coding in various applications.
