Description

technical field [0001] The invention relates to the field of optimal soft measuring instruments and methods, in particular to a sea clutter optimal soft measuring instrument and method based on fruit fly optimization algorithm to optimize RBF fuzzy neural network. Background technique [0002] In the radar field, the echo signal reflected from the seawater surface is called sea clutter, which is related to various factors such as sea conditions, wind tides, and radar parameters. For coastal warning radars, shipboard radars and other radars working in the marine environment, serious sea surface reflection echoes will affect the detection and tracking performance of sea surface targets. It is important to grasp the nature of sea clutter and establish an accurate sea clutter model. A prerequisite for analyzing and improving radar performance. The statistical properties of sea clutter include amplitude properties and correlation properties. Correlation properties of sea clutte...
