Do all radar systems have the capability to operate in both 90 degree and 360 degree modes?

Radar systems vary significantly in design and functionality, and not all of them are built to operate in both 90-degree and 360-degree modes. The capability to switch between these modes depends on the specific radar technology and its intended applications. While some advanced radar systems do provide the flexibility to operate in both modes, many basic systems are designed for either one or the other, limiting their operational versatility.

In general, a radar that operates in 90-degree mode is typically focused on a specific sector, which can be advantageous for target tracking within that confined range. Conversely, 360-degree mode allows for a full scan of the surrounding environment but requires different mechanical setups and processing capabilities. Therefore, stating that all radar systems have this dual functionality is inaccurate, confirming that the answer is indeed false.
