METHOD FOR INSTANTANEOUS PROCESSING OF THE GLINT NOISE AND TRACKING MONOPULSE RADAR RECEIVER CARRYING OUT THIS METHOD

Abstract

Method and apparatus for instantaneous processing of the glint noise in a monopulse radar. The radar antenna receives a sum signal S and a difference signal Δ whose phases vary as functions of time. Successive derivatives Q.sup.(k) of order k, are calculated as a function of time from k=0 to k=N'. Also, the scaler product Q=S×Δ of the sum signal and difference signals is calculated. Then, successive derivatives P.sup.(k) of order k are calculated as a function of time from k=0 up to k=N'. Also, the power P=|S|2 of the signal received, which is equal to the square of the modulus of the sum signal S, is calculated. Next, a plurality of derived angle-error measurement operators (εk) are calculated such that a εk =Q.sup.(k) /P.sup.(k). Finally, a combined angle-error measurement operator ε is calculated such that ##EQU1## The weighting coefficients β.sub.κ are coefficients representing the quality of the associated derived operator ε.sub.κ relative to the angle-error measurement of the barycenter of the target.
