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

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.
