The invention relates to a phased array antenna by means of which, besides normal radar transmissions, also a guidance of a number of semi-active homing missiles towards a number of targets can be effected. The main problem to be solved here is that a rear-reference signal for each missile remains present to a sufficient extent also during the periods covering normal radar transmissions. The invention solves this problem by transmitting rear-reference signals for all missiles deployed simultaneously with radar transmitter signals.
[ I claim:] [1.] A phase array antenna system provided with a phased array antenna for generating a pencil beam, designed for realizing radar transmissions and for the periodical illumination of selected targets for the guidance of missiles during their flight towards the selected targets, wherein each selected target is illuminated with an individual RF frequency and wherein each missile on its way to a selected target is provided with a reference signal having a corresponding individual RF frequency, characterized in that the phase array antenna system...
