Publication number: 20110070857Abstract: Systems and methods related to the detection of incoming wireless signals. An antenna array is synthesized by having a single antenna, coupled to a receiver, spatially translated along an arbitrary trajectory. As the antenna is being spatially translated, a data processing means samples the incoming signal based on a clock signal provided by a system clock. By sampling the incoming signal at different times at different spatial locations on the arbitrary trajectory, the system acts as a synthetic antenna array. The different samplings of the incoming signal at different times and positions provide signal diversity gain as well as different readings which can be used to detect an incoming signal. The invention is applicable to detecting a wireless communications signal or a GNSS signal under various conditions. The system may include at least one sensor which can provide data for use in calculating data related to the arbitrary trajectory.Type: ApplicationFiled: September 17, 2010Publication date: March 24, 2011Applicant: Her Majesty the Queen in Right of Canada as represented by the Minister of National DefenseInventors: John Nielsen, Gerard Lachapelle, Ali Broumandan

Patent number: 7274324Abstract: A path in three-dimensions for an object in flight is determined according to a radar signal reflected by the object. The radar signal is transmitted at an offset angle from horizontal sufficient to capture the object within the transmitted radar signal. The transmitted radar signal is reflected by the object to form a reflected radar signal containing an indication of a position of the object. The reflected radar signal is received and used to determine two-dimensional position information for the object by detection of the indication of the position of the object in the received radar signal. Position information is derived in three-dimensions from the position information in two-dimensions. The path information representative of the path for the object is obtained from the position information in three-dimensions based on an optimization of a curvature of said path information.Type: GrantFiled: July 8, 2002Date of Patent: September 25, 2007Assignee: Her Majesty the Queen in Right of Canada as Represented by the Minister of National DefenseInventors: Rhonda L.

Patent number: 4266208Abstract: Frequency division of microwave signals may be done using heterodyne conversion but there are limits to the ultimate instantaneous bandwidth that can be down-converted using this method and any frequency aberrations of the local oscillator show up at the output. It is also known to down-convert microwave signals by using a varactor divide-by-two system. However, to divide by factors greater than two, these dividers must be cascaded which results in losses that must be compensated by amplifiers. The present invention alleviates the foregoing problems by providing a single-stage analog microwave frequency divider which will divide microwave signals by four. The divider comprises a substrate having an input microstrip transmission line capacitively coupled to a resonator formed of first and second spaced apart parallel microstrip transmission lines of predetermined length.Type: GrantFiled: April 16, 1979Date of Patent: May 5, 1981Assignee: Her Majesty the Queen in right of Canada, as represented by the Minister of National DefenseInventor: William D.
