What does the AN/APR family of Radar Signal Detection Systems (RSDS) analyze to identify radar weapon systems?

The AN/APR family of Radar Signal Detection Systems (RSDS) is designed specifically to analyze radio frequency signals. This capability is vital for identifying radar weapon systems because these systems operate within the radio frequency spectrum. By monitoring and interpreting the characteristics of these signals, the AN/APR systems can detect and classify various radar systems, providing crucial information for operational assessments and tactical responses.

The focus on radio frequency signals allows these systems to effectively differentiate between various radar types based on their distinct signal patterns and modulation techniques. Other forms of signals, such as optical, acoustic, or infrared signals, do not serve this purpose in the context of radar detection. Each of those categories is used for different sensing technologies, which are not applicable to radar signal detection in the way that radio frequency analysis is. This specificity highlights the importance of radio frequencies in radar technology and the effectiveness of the AN/APR systems at utilizing this aspect for military and defense applications.
