Abstract: 1411027 Automatic control of course MOTOROLA Inc 10 July 1973 [21 Sept 1972] 32883/73 Heading G3R [Also in Divisions H3 and H4] A radiating-target seeking object is guided in azimuth and elevation by a system having a plurality of sensors 21 ... 24 (X-band aerials) which are connected sequentially to respective sample and hold circuits 51 ... 54 and at the end of each sampling cycle the held values are compared in respective azimuth and elevational pairs at 69, 66 to produce controlling signals 25, 26. For this purpose the outputs of the comparators are integrated at 74, 72. The transmitter produces pulses, e.g. of 2.5 Ás width, the frequency being varied in ramp form during each pulse. The received signals are heterodyned with a local oscillator at 93, amplified at 94 and passed through an acoustic surface wave compression filter 95 having a quartz substrate Fig. 4 which, because of the dispersive delay of this device, shortens the pulse length to e.g. 0.1 Ás. After further amplification at 96 they pass to the sample and hold circuits 51 ... 54 which comprise a fast acting F.E.T. turned on briefly by the sequencer 81, and a small capacitor from which the value is transferred by amplification to a larger capacitor Fig. 6 (not shown). This device blocks spurious signals, e.g. reflected signals, arriving more than 20 n.s. after the first. The sequencer is controlled by the output of amplifier 96 via a threshold detector 102 which blocks signals below a given magnitude. At the end of each cycle the sequencer simultaneously closes switches 59, 63 to connect the held values to the comparators.
