Abstract:
A method for remotely measuring a characteristic of one or more targets at a plurality of ranges along an antenna aiming line, comprising the steps of:transmitting pulses along said antenna aiming line said transmitted pulses having predetermined characteristics,in between transmission of pulses, receiving reflected signals from one or more targets along said antenna aiming line, said received signals having attributes, said attributes being dependent upon said characteristics of said transmitted pulses and upon a value of said characteristic of said one or more targets at each of said plurality of ranges along said antenna aiming line, said plurality of values of said characteristic at said plurality of ranges being referred to herein as a distribution,using said distribution of values of said characteristic at each of a plurality of ranges along said antenna aiming line as variables in a substantially linear system of equations having a plurality of equations, each equation having a sum of one or more terms where each term is the product of a coefficient having a known value derived from the pulse forms of the transmitted pulse pulse train and an unknown quantity which is referred to herein as a variable, with the plurality of variables in said equations defining a matrix the elements of which are said variables and wherein values of said variables are set equal to the value of said characteristic of said one or more targets at said plurality of ranges along said antenna aiming line, andsolving said substantially linear system of equations to derive values for said variables.
