Radar Performance Calculation
Various factors can impede and constrain the effectiveness of radar systems, including noise, interference, and clutter signals originating from diverse sources. It is essential for each radar site to be meticulously designed and equipped with devices aimed at mitigating the adverse impacts of rain and sea clutter, thereby improving the likelihood of target detection during each scan. Additionally, the radar system should be engineered and installed to minimize false echoes, which can result from side lobes or reflections from nearby structures. When choosing a radar system and determining the measuring frequency, it is crucial to consider regional conditions, such as heavy rainfall.
CARPET3
To elevate the performance of radar systems to the required standard, numerous technological solutions exist. Common approaches include increasing average transmission power, utilizing larger antennas, employing circular polarization, reducing receiver noise, implementing sector blanking, and enhancing the processing and filtering of both transmitted and received signals.
We can conduct a thorough analysis of a VTS radar performance utilizing the Computer Aided Radar Performance Evaluation Tool (CARPET3). This involves calculating the detection probability of a Vessel Traffic Service (VTS) radar.
Additionally, we can aid in identifying optimal VTS radar positions by generating radar coverage diagrams. These diagrams will be based on Digital Terrain Elevation Data (DTED), including datasets such as the SRTM Worldwide Elevation Data (1-arc-second Resolution, SRTM Plus V3).
Google Earth
Furthermore, we can compile a data file representing radar coverage for visualization in Google Earth, providing a comprehensive and visually accessible representation of the radar deployment.
