摘要： A code generator produces one sequence of coded pulses having a predetermined code pattern. This sequence of coded pulses is transmitted to a remote point and received from the remote point to provide a replica of the sequence of coded pulses. A correlator is coupled to the generator and receiver responsive to the sequence and its replica to produce due to the predetermined code pattern an impulse output only when the sequence and its replica are time coincident and a zero output at all other time relationships between the sequence and its replica.

摘要： A high gain, primary receiving antenna and a single scannable auxiliary lar antenna array are utilized. The auxiliary linear array is coupled to means for forming multiple directive narrow receiving beams simultaneously on the auxiliary array, each of which are scanned over an assigned segment of space to locate and isolate a respective one of a plurality of interfering or jamming signals which are also contained in the signal received by the primary antenna. The interfering signals are cancelled by separately adjusting the phase and amplitude of each one of the interfering signals received and then feeding them to a respective signal subtractor coupled to the output of a receiver connected to the primary antenna.

摘要： A relatively narrow beamwidth (10.degree. or less) receiving antenna patt is formed at the receiver end of a radio frequency transmission link where a plurality of radiating sources are operating in a dense communications environment. The antenna pattern comprises the difference between two antenna receiving patterns where the beamwidth of one pattern is wider by a predetermined angular amount than the other pattern. In the preferred embodiment, a phased linear array of antenna elements is operated as two sets of elements wherein one set of elements comprising a number of elements less than the total number of elements provides a beamwidth that is broadened by a predetermined angular sector greater than the beamwidth formed by the entire array. The antenna elements are progressively phase shifted to provide overlapping beam patterns and the pattern of one set of elements is scanned so that one side of both patterns are substantially coincident. The received signals from the elements developing the two antenna patterns are respectively combined and linearly subtracted to provide cancellation of all the received radiation except over the small angular sector defined by the difference between the two patterns.

摘要： Multiple interference sources are independently acquired, tracked and canled in a multi-element antenna array where the number of antenna elements n is an integer power of the base 2, i.e. n=2.sup.M where M is the number of sources desired to be cancelled. The antenna elements are selectively coupled to sets of n/2 phase shifters in respective closed loop control circuits and operate in phase controlled sets, one for each interference source. The phase of the received signal incident on one half of the elements in each set is independently adjusted relative to the other half, for each desired null in a separate control loop, such that for a particular interfering source each antenna element of the set has one corresponding neighboring element in a pair of elements whose phase mutually differs by 180.degree. at the space angle of the arrival of the interference wavefront relative to the axis of the antenna. This produces a substantially infinite null in the direction of arrival of the particular interfering wavefront and thus complete cancellation of that interfering source is effected. This null is retained as other interfering sources are independently acquired, nulled and tracked by a respective different set of n/2 elements in the same array.

摘要： A pulse code modulation communications system employing orthogonally sepaed noise code mate pairs having autocorrelation functions which upon detection in a matched filter and addition compress to a lobeless impulse. A mate pair of bi-polar digital noise codes are impressed on respective RF carriers generated by the same frequency source with one code mate being transmitted separately as a vertically polarized wave while the other code mate is transmitted separately as a horizontally polarized wave. The polarized RF carrier signals containing the code mates are respectively received by horizontally and vertically polarized antennas coupled to radio receiver apparatus which provides respective received signals containing the code mates. The code mates are then detected by matched filters which operate to compress the code mates. The compressed code mates are then linearly added to provide an output signal comprising a lobeless impulse signal.

摘要： An orthogonal code division multiple-access communications system comprised of a plurality of transceivers respectively employing orthogonal noise code mate pairs of a type having autocorrelation functions upon detection which when linearly added together compress into a lobeless impulse and wherein the same single time slot is utilized by all of the users in the system. Each user is assigned a different unique noise code pair consisting of code mate pairs that are selected from a subset of multiplexed noise codes whose cross-correlation function value is equal to zero at a time when all the code mate pairs compress to an impulse, i.e. .tau.=0. The described arrangement enables random access, or direct call-up, to be accomplished with no interference between the users while using different noise codes for each user.
