The radar process involves several key steps. First, the radar system generates and transmits pulses of radio frequency energy through its antenna. These pulses travel through the air and, upon encountering an object, are reflected back to the radar antenna as echoes. The radar receiver then captures these echoes and converts them into electrical signals. By measuring the time it takes for the pulses to travel to the object and back, the radar system calculates the distance to the object. The direction from which the echoes return indicates the rolling of the object.
This information is then used to create a visual representation of the surrounding environment on a radar display, showing the positions and movements of detected targets.
Radar data processing involves several steps to convert the raw signals received by the radar into meaningful information. Initially, the received echoes are amplified and filtered to remove noise and improve signal quality. The processed signals are then digitized for further analysis. Signal processing algorithms are applied to extract relevant features, such as range, roll and speed of targets.
Techniques such as pulse compression, Doppler filtering and clutter removal are used to improve the resolution and accuracy of target detection. The processed data is then displayed on a screen, often with additional overlays and annotations to aid interpretation and decision-making. This processed radar data provides operators with clear, actionable information for navigation, surveillance or other applications
