Patent ID: 7852259

Claim:
A method for creating a tool for clutter filtering of broadband radar signals by obtaining a measure of an impedance of a target, wherein the method comprises the steps of: selecting a distance resolution (p(τ)); calculating a power spectrum (P(ω)) for a necessary transmit signal; estimating a target area profile (ρ(τ)) by using a correlation (g(τ)) between a radiated signal and received signal; calculating a target impedance Z(τ) as a function of time using a relation Z ⁡ ( τ ) = Z 0 ⁢ 1 + ρ ⁡ ( τ ) 1 - ρ ⁡ ( τ ) where Z 0 is the impedance of free space; and filtering out the target using the target impedance.
