Patent ID: 8193972

Claim:
A method for adaptive calculation of pulse compression filter coefficients for a received signal in a radar installation, which received signal is evaluated with the aid of a complex pulse compression mismatch filter, comprising: determining, using an electronic processor, a pulse compression filter coefficient set h(t) for an ideal theoretical received signal s(t) for a pulse compression mismatch filter, such that a pulse compression output signal results with a desired main-lobe-to-side-lobe ratio; and determining, using the electronic processor, a transformed set of pulse compression filter coefficients H opt (f) for the complex pulse compression mismatch filter H opt (f) for a distorted received signal, using the following rule: H opt ⁡ ( f ) = S ⁡ ( f ) · H ⁡ ( f ) · S v * ⁡ ( f )  S v ⁡ ( f )  2 where S(f): Fourier-transform of an undistorted received signal s(t), S v (f): Fourier-transform of a distorted received signal s v (t), S v *(f): complex conjugate of S v (f), H(f): Fourier-transform of the pulse compression mismatch filter h(t).
