Patent ID: 7961138

Claim:
An operational radar angle detector apparatus to rapidly identify a range of optimum depression angles with a Graphical User Interface (GUI) in a computer, comprising: a means for initializing said GUI; said computer being connected to an airborne radar system and having a computer program using a software package with a technical computing language and interactive environment for algorithm development, data visualization, data analysis, and numeric computation; a means for setting inputs in said GUI having a plurality of computer fields; the user selects a terrain-type input from a plurality of terrain-type inputs causing said setting inputs means to provide a dielectric constant setting in a dielectric constant computer field and a conductivity setting in a conductivity setting computer field; a carrier frequency input is entered into a carrier frequency input computer field; a means for calculations is activated and said calculations means automatically selects a plurality of radar algorithms to populate an optimum depression angles field based on said terrain-type input, said dielectric constant setting, said conductivity setting, and said carrier frequency input; said optimum depression angles field provides said range of optimum depression angle values; said calculation means provides a cross-correlation matrix of a plurality of horizontally and vertically polarized electromagnetic waves where a plurality of optimum depression angles are identified for the purposes of reflection, and identifies a ground penetration angle; and said calculations means sends an optimum depression angle result directly to said airborne radar system that correlates a plurality of radar return properties that are generated in multiple, widely disparate bands.
