Abstract

960,836. Radio receiving circuits; radar. COMPAGNIE FRANCAISE THOMSONHOUSTON. March 17, 1961 [March 18, 1960], No. 9881/61. Headings H4D and H4L. An antenna 4 via a duplexer 5 supplies a radar receiver comprising a frequency changer 7, an I.F. stage 8 having a pass-band wider than normal, a gate circuit 10, an I.F. stage 9 having a normal pass-band, a detector 11, and a video-frequency amplifier 12. An auxiliary channel comprising a frequency changer 13 and I.F. amplifier 15 is supplied by an omnidirectional antenna 14, and in the presence of interfering signals above a predetermined amplitude operates the gate 10 to block the signals from the I.F. stage 8. It is stated that interfering signals below this amplitude are passed by the stage 8 but are greatly attenuated by the stage 9.
