Passive radar systems work by detecting signals from non-radar sources, such as commercial radio or television broadcasts, instead of emitting their own signals. These systems use existing electromagnetic signals in the environment, making them harder to detect and less susceptible to jamming. Passive radar can be used for surveillance, target detection, and tracking in both military and civilian applications. Its primary advantage is stealth, as it does not transmit any signals that could give away the system’s position. Passive radar is increasingly used in applications where reducing detection risk is a priority.
