METHOD FOR ANTI-JAM PROTECTION OF COHERENT-PULSE RLS AGAINST COMBINED JAMMING

摘要

A method for protection of coherent-pulse radar stations with packet modulation of frequency of sounding pulses against combined jamming, with phase (time) and polarization, or spatial, filtration. Sequence of phase and polarization filtration depends on the ratio of the levels of power of active and passive components of combined jamming determined in analyzer of the level of components of combined jamming, analysis of the level ratio is carried out at the intervals of range where according to information obtained from the map of passive interferences are present. If the level of passive component of jamming exceeds the active one first phase filtration of signals is carried out, and then polarization filtration, if active component of jamming exceeds the passive one first polarization, and then phase filtration are carried out.
