Enhancing the detection capability of secondary radar for dense targets

Abstract： Secondary radar systems primarily detect cooperative targets through an interrogation-response mechanism and are extensively applied in fields such as air traffic control. To address the issue of declining detection probability for dense targets in traditional secondary radar systems, this pager analyzes the mechanism by which random response delay enhances the detection probability for dense targets, formulates the underlying mathematical problems, and validates the findings through theoretical derivations, calculations, and Monte Carlo simulations. The results demonstrate that the random response delay technique can effectively improve the detection performance of secondary radar systems for dense targets. Furthermore, under the premise of meeting detection probability requirements, the number of detectable dense targets exhibits a linear step-like relationship with the number of response positions.
