Abstract: 1,272,000. Radio navigation. DEFENCE, SECRETARY OF STATE FOR. 15 May, 1970 [20 May, 1969], No. 25695/69. Heading H4D. An instrument landing system (I.L.S.) utilizes the transmission from a first aerial of a frequency-modulated wave and from a second aerial waves each with a frequency modulation related to that from the first aerial and one of which is amplitude-modulated at 90 Hz and the other at 150 Hz. At the aircraft receiver the mixer produces an output signal carrying the 90 Hz and 150 Hz modulations; these are applied to a conventional I.L.S. receiver, Fig. 4 (not shown).  Transmitter details, Fig. 3.-As applied to the glide slope, a frequency modulator 6 produces a signal of centre frequency 1000 MHz and sinusoidal frequency deviation  100 MHz. This signal is (a) is delayed by t 0  and then converted in varactor 8 into an F.M. signal centred on 5330 MHz, the latter being amplified and radiated from upper aerial TA 2 , and (b) is converted in varactor 7 into an F.M. signal centred on 5000 MHz, the latter being amplitude-modulated (A.M.) at 0 Hz and, after a delay 2t 0 , being amplitudemodulated at 150 Hz, both A.M. signals being radiated from lower aerial TA 1 . The delay 2t 0  and the aerial separation determine the sensitivity (amplitude of indication relative to departure from glide path) of the system, whilst the delay to determines the glide slope angle. Monitoring.-The radiated signals are monitored by a probe mounted on the reflector of each aerial, the probes being connected to a receiver of the kind provided in an aircraft, Fig. 5 (not shown). Modifications.-The two F.M. signals may be spaced by 20 MHz, the receiver then incorporating a 310 MHz oscillator and a mixer to afford a 330 MHz signal, Fig. 6 (not shown). The oscillator 2, Fig. 3, of the transmitter may be modified so that the receiver output is at the I.F. of a conventional I.L.S. receiver, Fig. 7 (not shown). And delay to, Fig. 3, need not be exactly half 2t 0 : if delay to is above the exact figure the glide path is hyperbolic.

Title: Ultrasonic microwave doppler intrusion alarm system
IPC: G01S13/56
Filed: 1973-05-30
Abstract: 1386223 Intruder alarms E-SYSTEMS Inc 30 May 1973 [20 July 1972] 25711/73 Heading G4N [Also in Division H4] An intruder alarm system comprises ultra-. sonic and microwave movement detection units, an integrator and signal level detector coupled to the microwave unit, a test circuit responsive to fault conditions, and means for providing an alarm signal when movement indication signals co-exist at the unit outputs. A central housing (10) (Fig. 1, not shown) contains a microwave transmit/receive antenna (20) and utrasonic receiver elements (18), outboard housings (12), (14) containing ultrasonic transmitting elements (22). In Fig. 2 the ultrasonic 30 and microwave system 32 are connected to logic 34, which gives the alarm signal when system 30, 32 gives simultaneous outputs. A line 38 from a central controller (24) (Fig. 1, not shown) applies selftest signals to the systems to continuously monitor their operation. Signals are also provided by the systems to indicate if the ultrasonic and microwave oscillators are working, and these signals are passed to logic 40. Fig. 3 (not shown) illustrates the microwave system in detail. The doppler movement signal, if present, is rectified and integrated and, if above a certain level, passed to logic 34. An attenuator 50 injects a test signal from line 38 into the pre-amplifier 48, the signal simulating a moving intruder. A signal from mixer 44, fed to logic 40 of Fig. 2, indicates if oscillator 46 is operative. Fig. 6 illustrates the ultrasonic system. Outboard units 108, 114 contain the ultrasonic transmitting elements 22, and central unit 104 contains receiving elements 18. The doppler signal from mixer 120 is filtered and amplified at 122 and then rectified, integrated and level detected as in the microwave receiver. The signal is then passed to logic 34. The test input from the controller unit is a square wave provided on line 130. This pulses a modulator 128 which gives bursts of signals within the doppler passband. The test bursts are then applied to filter-amplifier 106 and the system function therefore checked. Signals are also provided from units 108 and 114 to a unit 112 which both monitors the units 108, 114 for correct functioning and also supplies them with ultrasonic power from oscillator 128. Signals on lines 166, 158 will indicate tampering with units 108, 114 respectively, e.g. disconnection of them from the ultrasonic power supply, shorting of the unit connections or a failure of oscillator 118. Oscillator 118 may be arranged to give a frequency changing with temperature in the same way as the transmitter transducer resonant frequency changes to always ensure maximum power output. Detailed circuits of the microwave oscillator 46, units 108, 114, oscillator 118 and modulator 128 are given. Reference has been directed by the Comptroller to Specification 964,752.

Abstract: 1,108,016. Aerial direction control. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 25 June, 1965 [25 June, 1964], No. 26335/64. Heading H4D. The Specification describes a control system for causing an antenna to track a communications satellite. A digital computer is provided, having at its five inputs the following:- Input (1) Predicted orbital position data. Input (2) Miscellaneous corrections to above. Input (3) Clock signals. Input (4) A direction-error signal from a static split antenna system, integral with the main antenna and receiving signals from the satellite. Input (5) Signals representative of the antenna direction. From the above inputs, the computer produces an elevation error signal, which is sent, via a digital to analogue converter, to the antenna elevation positioning motor. A tacho-generator coupled to the antenna provides a rate aiding signal. The computer is programmed to calculate azimuth and elevation signals from the orbital data, to apply any known corrections to the signals, to further correct these signals by comparison with the output of the tracking receivers and finally to compare these signals with the signals representative of the antenna direction so as to produce elevation and azimuth error signals. To initially acquire the satellite when it appears over the horizon, the two switches are moved to their upper (position) positions, and the antenna positioned manually until its actual position, as displayed, is seen to be the same as the displayed computed position. The control available by use of the orbital data alone is sufficiently accurate to enable reacquisition of the satellite if it is lost during a passage near the zenith, or through interruption of the tracking.
