1. A method for processing glint noise in a monopulse radar having an antenna which receives a signal and produces sum signal S and difference signal Δ

  • whose phases vary as functions of time, comprising the following steps;

    calculating successive derivatives Q.sup.(k) of order k, as a function of time, from k=0 up to k=N'"'"' (N'"'"'≧

    2), of the scalar product Q=S.Δ

    of the sum signal S and difference signal Δ

    ;

    calculating successive derivatives p.sup.(k) of order k, as a function of time, from k=0 up to k=N'"'"', of the power P=|S|2 of the signal received, which is equal to the square of the modulus of the sum signal S;

    calculating (N'"'"'+1) derived angle-error measurement operators ##EQU28## and calculating a combined angle-error measurement operation ε

    such that ##EQU29## in which (N'"'"'+1) weighting coefficients β

    .sub.κ

    , for k=0 to k=N'"'"', are coefficients depending on the quality, relative to the angle-error measurement of the barycenter of the target, of the derived angle-error measurement operators ε

    78 which correspond thereto.
