What does the pulse width (PW) in a RADAR system determine?

The pulse width (PW) in a RADAR system specifically refers to the duration of the transmitted pulse. This parameter is crucial because it directly influences the RADAR's ability to differentiate between targets and accurately measure distances. A shorter pulse width allows for higher resolution, enabling the system to distinguish closely spaced objects. Conversely, a longer pulse width can cover greater distances but may reduce resolution in terms of target separation.

Understanding the pulse width is essential for interpreting how the RADAR system functions and its performance in various applications. It is fundamental in the design and operation of RADAR systems, affecting not only the quality of the received signals but also the overall capability of the system to detect and track objects. Therefore, identifying the pulse width helps in understanding its role within the larger context of RADAR technology.
