RADAR system stands out from other sensing devices and systems because of its efficiency in all-weather conditions and precision in detecting and ranging targets. However, electronics RADAR is constrained by its bandwidth bottleneck, signal-to-noise ratio (SNR), and limited frequency tunability. This project focuses on the development of random/frequency hopped LFM Photonic RADAR for mitigating interferences and attackers in multi-RADAR environment.
