WebApr 12, 2024 · Both clutter and jamming can increase the noise level and reduce the signal-to-noise ratio (SNR) of the radar, making it harder to detect and identify the true targets. Signal-to-noise ratio (SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. SNR is defined as the ratio of signal power to the noise power, often expressed in decibels. A ratio higher than 1:1 (greater than 0 dB) indicates more signal than noise.
