Title: Signal processing apparatus suitable for use in amti radar system

IPC: G01S13/534
Filed: 1965-10-05
Abstract: 1,120,293. Pulse radar. NORTH AMERICAN AVIATION Inc. 5 Oct., 1965, No. 42295/65. Heading H4D. In an airborne moving target indicator radar, using a non-coherent pulse system, the radar return pulses are applied to a unipolar video detector to provide a beat frequency between the ground clutter and moving target spectra. A filter rejects the non-moving target signals and accepts signals from targets within a selected range of ground velocities. Range gating of the received signals is effected by a scan converter, which feeds the band-pass filter, the output from which controls the display device. The scan converter may provide either optical or electrostatic storage and has orthogonal read and write modes. The system provides clutter-referenced signals, independent of the radar motion and requires only a single Doppler band-pass filter. The non-coherent radar 10, Fig. 1, feeds the scan-converter 12 through the diode detector 11. The band-pass Doppler filter 13 is supplied from 12 and controls the indicator 14. The transmitted spectrum, Fig. 2a, of carrier frequency f o , produces a received spectrum. Fig. 2b, having two envelopes, 16a and 16b corresponding to clutter and moving target returns respectively, the latter being Doppler-shifted by the amount f TD . The effect of diode 11 is to provide the folded spectrum, Fig. 2c, having the clutter envelope 16c and the target components 17, corresponding to the beat frequency between the moving target spectrum and the ground clutter spectrum. The ground clutter is represented by the zero frequency signal 15c regardless of the radar motion. The target beat frequency is passed through the band 18, Fig. 2d, of the filter 13 and the clutter, 15c is rejected. The variation of signal intensity at range R 2 , Fig. 3, indicates the presence of an A.C. signal having a spectral content corresponding to 17 of Fig. 2c. In a modification of the band-pass filter 13, to prevent the spread of the clutter spectrum into the band-pass zone due to increasing radar velocity, two filters having contiguous pass bands 18a, 18b, Fig. 8, are employed. A separate threshold control is associated with each filter so as to relate the threshold level of each component filter to the clutter spectral remnant 115a spreading into the band-pass.

Title: Data demodulator employing comparison

Filed: 1970-09-08
Abstract: 1324189 Data demodulators SANDERS ASSOCIATES Inc 8 Sept 1970 [17 Sept 1969] 43037/70 Heading H4P A demodulator comprises an exclusive-OR gate 14 for comparing a data modulated signal LS1 with a delayed version LS2 of the signal to provide a comparison signal CS having first and second amplitude values dependent on the identity and non-identity respectively of the signals LS1, LS2 and a digital filter 16 including a counter 18 for counting in first and second directions in response to the first and second amplitude values respectively to provide an indication of the modulating data. FSK signals are fed via a wire, cable, microwave or radio link to a receiver 10, a band pass filter 11 and an amplitude limiter 12 which clips the sinusoidal FSK signals. A delay 13 which may be a shift register supplies the signal LS2 to the gate 14 which detects changes in the modulating frequency due to changes from mark to space data or vice versa. An inverter 15 produces a signal CS which is predominantly "low" for mark data and predominantly "high" for space data. The signals CS and CS are fed to the down and up controls of the counter 18. "AND" gates 19, 20 are connected to the mark, M and space, S outputs of the counter 18 and supply enabling and disabling signals to an "AND" gate 23 via which clock pulses are fed from a source 26 to the counter. When the signal CS is predominantly "high" or "low", i.e. during space or mark tones, the gates 19, 20 inhibit the gate 23 but at a change between mark and space tones the forms of the signals CS, CS cause the "low" outputs of the gates 19, 20 to enable the gate 23 so that the counter counts up when CS is "high" and down when CS is "low" thereby filtering the signal CS to provide low level (mark) and high level (space) signals at the counter outputs. These signals are fed via the gates 19, 20 to a sampling network 17 comprising a JK flip-flop which reconstitutes the mark-space data signal EDO. To reduce the effects of jitter, an exclusive-OR gate 25, which receives the signals #CS and EDO, controls a switching circuit 24 to enable clock pulses CP1 at a high rate to be supplied to the counter during counting towards its "mark" or "space" states and to enable clock pulses CP2 at a low rate to be supplied during fall back intervals of the comparison signal which cause the counter to count in an opposed direction. The digital filter may be replaced by a digital or analogue integrator and the demodulator may also be used in PSK systems.

Abstract: 967,301. Latch fastenings. AHRENDLIBRA N.V. Dec. 14, 1960 [Dec. 18, 1959], No. 43062/60. Heading E2A. A latch mechanism comprises a pivoted bolt mounted on a cylindrical shaft which is rotatably housed in a tabular casing, the bolt being spring-urged towards its locking position and the shaft being provided with an actuating member which extends into a slot in the casing for co-operation with operating means to move the latch bolt to its unlocked position, the arrangement being such that the actuating member lies wholly within the circumference of the outer surface of the casing. In the arrangement shown in Fig. 1, the bolt 23 is turned towards its unlocked position against the action of spring 27 by operating means co-operating with an actuating member 31 extending from the shaft into a slot in the casing 21 of the mechanism, the operating means preferably comprising the connecting spindle of push-pull handles mounted on opposite sides of a door. As shown in Fig. 2, the cylindrical shaft houses a dead bolt 41, and the actuating member 42 extends from the dead bolt through apertures in both the shaft and the casing. The bolt is rotated by means of the spindle interconnecting push-pull handles, as before, but in this instance the spindle is provided with a flat for engagement in the recess 51 of the actuating member. Thus by rotating the spindle, for example by means of a key-operated mechanism in one of the handles, the bolt 41 may be moved axially of the shaft 40. In both embodiments the bolt is apertured and is keyed to the shaft by means of projections in the wall of the aperture engaging with slots in the shaft. The Specification also describes a housing and rose plates for mounting the latch mechanism in a door, the housing being generally cylindrical and having screw-threaded ends to receive the rose plates.
