Abstract

1516722 Radar LIGNES TELEGRAPHIQUES ET TELEPHONIQUES 3 July 1975 [26 July 1974] 28052/75 Heading H4D The Doppler radar described in Specification 1,465,925 is simplified by the removal of the capacitive diode 13 and the use instead of the capacitive diode effect of the collector-base junction of the transistor of the microwave oscillator 31. Optimum operating conditions are given. A practical strip-line embodiment is described, using an output line 32 having a stub 37 tuned to the multiple frequency nf o .
