Radar signal processing is a field of study that focuses on analyzing and interpreting signals emitted by radar systems in order to extract useful information and make informed decisions. This involves techniques such as filtering, detection, estimation, tracking, and image formation to enhance the detection and classification of objects in radar images. Researchers in this area aim to improve the accuracy and reliability of radar systems for various applications, such as surveillance, navigation, and weather forecasting. Additionally, advancements in radar signal processing have led to the development of new technologies like synthetic aperture radar (SAR) and inverse synthetic aperture radar (ISAR) for high-resolution imaging and target recognition.
