Filed: 1969-12-17
Abstract: 1277667 Multiplex radio signalling NIPPON ELECTRIC CO Ltd 17 Dec 1969 [19 Dec 1968] 61556/69 Heading H4L In a known arrangement for transmitting a plurality of carrier waves of frequency f 1 , f 2 , f 3  &c., separated by equal frequency increments f, over a common aerial 7, Fig. 2, bandpass filters 2, 4, 6 are tuned to the frequencies f 1 , f 2 , f 3  respectively and couple the carrier waves via circulators 1, 3 and 5 to the aerial. Carrier f 1 , is subject to phase distortion by reflection in filter 4 and carrier f 2  similarly receives phase distortion in filter 6. Reflections from the aerial 7 pass through the circulators 1, 3, 5 and are absorbed in a non-reflecting termination 8. Fig. 10 shows the phase distortion in a bandpass filter centred around frequency f 2  and having reflecting characteristics at the frequencies f 1  and f 3 . Carrier wave f 2  is subject to second order phase distortion as shown by full line 2 and waves f 1  and f 3  are subject to phase distortion of the first order as shown by lines 1 and 3 the slopes being positive and negative respectively. The invention provides an arrangement for reducing this delay distortion and as shown in Fig. 3, carrier f 2  passes via bandpass filter 4 and circulators 3, 10, to a junction 9 where it is reflected by bandpass filters 2, 6 tuned to frequencies f 1 ,f 3  respectively. Filter 2 produces delay distortion 3 of negative sense, Fig. 11, and filter 6 produces delay distortion 1 of positive sense and these distortions cancel, leaving only the second order phase distortion 2 in the transmitted signal. Carrier waves f 1 , f 3  are not reflected by the filters and pass via circulator 10 to the aerial 7 with no first order phase distortion. Reflected signals from the aerial are absorbed at 8. Similar arrangements for combining four and six carrier waves are described. For reception of the carrier waves the direction of the circulators is reversed.

Title: SSR receiver with degarble facility
IPC: G01S13/78
Filed: 1979-05-29
Abstract: The received response signals may comprise interleaved or superimposed pulses from separate transponders, resulting in the latter case, in garbling to the extent that the information content is adulterated. To improve false alarm suppression and facilitate recognition of interleaved response signals capable of being degarbled, the response signals are processed at 1 to give their pulses a standardised pulse width in a series, and then fed into a digital delay line (2) able to accommodate at least two complete response signals in series. The delay line (2) is provided with tappings which form sampling zones with durations less than a standardised pulse width and with spacings equal to that of the pulses in the signals. The samples are then logic circuit analysed in a video analysis circuit (3) to form a frame coincidence pulses NR when a first valid response signal is detected and a degarble frame coincidence pulses DR when interleaved response signals are detected, whilst inhibiting the degarble pulse in a garbling or superimposed pulses situation, and when possible producing parallel mode read out of the information content, SP1 to C1. <IMAGE>
