How can environmental conditions degrade radar performance?

Environmental conditions degrade radar performance by creating clutter and attenuating the signal. Clutter from terrain, sea, or objects adds unwanted echoes that can resemble real targets, masking true returns and producing false targets. Weather and precipitation, such as rain, snow, or fog, absorb and scatter radar energy, which reduces the signal-to-noise ratio, shortens effective range, and can blur or hide targets. Additionally, atmospheric effects like refraction or ducting can alter beam paths, further distorting returns and reducing resolution. Altogether, these factors mean environmental conditions make targets harder to detect accurately and lower the ability to distinguish closely spaced objects, rather than enhancing performance.
