Searching parameter optimization method for high-speed moving object detection by phased array radar

Abstract

The invention provides a searching parameter optimization method for high-speed moving object detection by a phased array radar. The method comprises: step one, according to a combat need, a radar performance index and a searching spatial-domain parameter are determined; step two, a searching parameter optimization model is established; step three, searching parameter optimization is realized on the condition of constant-speed moving of an object; and step four, searching parameter optimization is realized on the condition of uniformity accelerated motion of the object. The method has the following beneficial effects: for a single large-spatial-domain high-speed moving object scene, an optimization model of an expected detection distance is established, so that restriction of a detection distance index can be eliminated effectively; an analysis is carried out by combining a typical high-speed moving object detection model and the object characteristic in an actual task is taken into consideration, so that an accurate searching parameter design can be realized; application demands on different motion conditions can be satisfied; the design process is simple and the calculation load is low, and improvement of the radar searching performance can be realized with the low costs; and the application range is wide and the method can be generalized to searching parameter design situations under other object scenes.

Problems solved by technology

However, the existing series of inventive methods mainly focus on proposing more optimization indicators from the new methodological level, assuming that the target obeys the premise of Swerling type I distribution, without considering the complex and changeable target characteristics in actual combat situations. When the target fluctuation model The result obtained when there is a mismatch is not optimal, so it has certain limitations
