Filed: 1970-10-06
Abstract: 1307260 Pulse radar A C COSSOR Ltd 6 Oct 1971 [6 Oct 1970] 47534/70 Heading H4D A secondary radar ground station comprises directional aerial 2 fed with coded pulses from transmitter 1 and a non-directional aerial 12 fed with a pulse at a predetermined zero bit position in the code. The code, which includes an address code allotted to the interrogated aircraft, is supplied from computer 3 and fed into register 4. AND gate 5 is enabled by computer 3 and the bits clocked out by 6 into AND gate 7 and hence to the transmitter 1. In the embodiment illustrated, the first zero bit position is used for feeding aerial 12. An inverter 8 converts the zero bit to a one and enables AND gate 9 which has a one applied from the Q output of monostable 10. A pulse is therefore applied to transmitter 11 and hence aerial 12. The gate 9 is subsequently disabled as the output Q is now zero until the monostable reverts back to its original condition i.e. only one such pulse is sent in each interrogation. The aircraft disregards the spurious pulse from 12 if in the main beam but if in a side lobe detects an erroneous code, the pulse from 12 then being comparable with those from 2, and rejects the interrogation.
