Title: Cooperative Radar and Reflector System.
IPC: F23K3/00
Filed: 1968-02-13
Abstract: 1,180,001. Pulse radar; interference suppression in radio receivers. SIERRA RESEARCH CORP. 13 Feb., 1968 [21 Feb., 1967], No. 7109/68. Headings H4D and H4L. A radar system which receives reflected signals from beacons which are shifted in frequency from the transmitted signals has two channels in its receiver, one for directly reflected signals and the other for the frequency-shifted beacon signals. Each channel includes a gate which is inhibited if noise &c. signals are too high, and the channel for the beacon signals also includes means for excluding directly reflected signals. The outputs of the gates are coupled to a display means. As described, a radar transmitter 3, Fig. 4, is coupled through a T/R box 2 to a directional scanning aerial 1 from which pulses of frequency f t  are transmitted. Pulses of frequency f t  are returned by reflecting targets and, in addition, pulses of frequencies f t   60 Mc/s. by beacon reflectors each comprising a horn 40 having a short waveguide section 42 containing a diode 44 which is rendered alternately conductive and non-conductive by a 60 Mc/s. oscillator 46. The received signal output of the T/R box 2 is connected to a mixer 4 having a local oscillator 5 offset in frequency from f t  by 30 Mc/s. Direct reflection signals are processed in a 30 Mc/s. I.F. amplifier and detector unit and are fed to a first input of a video combiner 30 through a gate 10 and a potentiometer 32. The output of the combiner 30 is fed to a P.P.I. display unit 7. Output signals from the mixer 4 are also fed to a limiter-amplifier 14 having a 100 Mc/s. pass band, the output of which is fed through a 30 Mc/s. notch filter 16 to the inhibit control line 12 of the gate 10. The limiter-amplifier 14 has the property that the strongest signal within its pass band blocks out weaker signals. Thus, if the wanted 30 Mc/s. signal predominates it alone is passed to the notch filter 16, where it is stopped and, as there is no output on the control line 12, the gate 10 remains open. If, however, noise predominates, there is an output on the control line 12, the gate 10 is inhibited, and there is no signal to the first input of the video combiner 30. A threshold control is provided by means of a battery 15 and a potentiometer 17, the arm of the latter being connected by a line 13 to the gate 10. Output signals from the mixer 4 are also fed through a 30 Mc/s. notch filter 28 to a limiteramplifier 24 which is similar to the limiter amplifier 14, and the output of which is fed to a second input of the video combiner 30 through a gate 20 and a potentiometer 34, and also through a 90 Mc/s. notch filter 26 to the inhibit control line 22 of the gate 20. In this way, if 90 Mc/s. signals, which represent one of the frequency-shifted beacon signals, predominate over noise they are passed through the gate 20 for display. A threshold control is provided as for the gate 10.

Abstract: 573,272. Television; electronic scanning. FARNSWORTH TELEVISION & RADIO CORPORATION. May 10, 1943, No. 7399. Convention date, April 1, 1942. [Classes 40 (iii) and 40 (v)] In a television scanning circuit in which the linescanning wave is modulated in accordance with the varying amplitude of the fieldscanning wave for correcting keystone distortion, the modulator 20 comprises two valves 25, 26 connected in push-pull, the grids of the valves being fed with linescanning waves of equal amplitude, but opposite polarity the cathodes being fed in parallel over lead 46 with the field-scanning waves and the anodes being fed through a balanced choke 35 and shunted by a resistance 32. The resistance 32 is of such a value that the output impedance of the valves 25, 26 is substantially purely resistive and the turns of the two halves of the choke are wound side by side to ensure close coupling and reduce leakage resistance, the effect of the arrangement being to remove from the modulated line-scanning wave the fundamental and higher-order frequencies of the field-scanning wave. The modulated line-scanning wave is fed through an amplifier 38 to the deflecting coils 42 of the cathode-ray tube 40. The linedeflecting saw-tooth waves of opposite polarity supplied to the modulator 20 over leads 16, 17 are generated by two similar condenserresistance timing circuits 7, 8 ; 12, 13 connected respectively to the anode and cathode of a valve 10, the grid of which is fed with s'quaretopped waves from a generator 2.
