What is the relationship between pulse width and average power in RADAR systems?

In RADAR systems, the relationship between pulse width and average power is significant because it relates to how energy is transmitted over time. A longer pulse width generally increases average power because the total energy transmitted is the product of the pulse width and the peak power.

When the pulse width is prolonged, the transmitter sends out energy for a longer duration, which elevates the average power over time since average power is calculated as the total energy divided by the time interval. Conversely, if the pulse width is shorter while the peak power remains constant, the energy transmitted in each pulse decreases, resulting in lower average power.

This principle illustrates why a longer pulse width can effectively increase the average power output of a RADAR system; more energy is emitted over a longer time frame compared to shorter pulses. Understanding this relationship is crucial for optimizing RADAR performance in various applications, such as target detection and ranging.
