What impact does bandwidth have on radar system performance?

The choice regarding how bandwidth impacts radar system performance is fundamentally tied to the principles of signal processing in radar technology. Bandwidth is directly related to the ability of a radar system to distinguish between different targets that may be close together in range.

When bandwidth is increased, the radar system can effectively transmit and receive a wider range of frequencies. This leads to improved range resolution, which allows for more precise measurement of distances to targets. In essence, a radar system with larger bandwidth can resolve two targets that are closer together than a system with narrower bandwidth could. This improved ability to discriminate between closely spaced targets enhances the radar's overall performance in various scenarios, such as in cluttered environments or in tracking multiple objects simultaneously.

While other options mention benefits like processing speed, size reduction, and power consumption, these do not relate directly to the core function of bandwidth in terms of resolution and discrimination, making the choice that emphasizes improved range resolution and target discrimination the most appropriate in the context of radar performance.
