Abstract: A process for detecting the harmonic motion characterizing a desired target. An exemplary method includes generating a radar image of the target utilizing a pulse doppler radar. A plurality of matched filter signals are generated in the receiver, each matched filter signal corresponding to a doppler profile of harmonic acceleration for the desired target. The matched filter signals are generated by an array of matched filters, with each matched filter signal corresponding to a predetermined doppler profile. The received radar image is then correlated to the matched filter signals to detect the desired target.

Abstract: A process for detecting and discriminating a particular target, such as an ambulating human, amidst an environment crowded with other objects or humans having similar doppler profiles to the desired target. A method according to one embodiment includes generating an initial radar image corresponding to a received doppler profile of a target, and generating a matched filter signal corresponding to the received doppler profile. The matched filter signal is correlated with subsequently received radar images to detect and discriminate the target.

Abstract: A hovering helicopter has a radar transmitter/receiver for transmitting radar pulses for illuminating a target for SAR imaging, and rotor blades for generating lift. Radar reflectors are on the rotor blades. The radar reflectors are oriented to reflect the radar pulses from the transmitter to the target as the rotor blades rotate. The radar pulses reflected by the moving reflector from the transmitter are timed to generate the synthetic aperture image using radar returns from the target. The receiver also receives blade returns directly reflected from the moving reflectors attached to the lift rotor blades. The receiver analyzes the blade returns to extract motion details of the reflectors and uses the motion details for motion compensation of target returns for SAR imaging.

Abstract: A LADAR system for coherently imaging a target within a volume has a modulated laser transmitter at a frequency and a receiver. The receiver has a plurality of lenses, each with its own detector. Each detector is supplied by a centrally located local oscillator tuned to the frequency. The paths from the local oscillator to each detector, as well as the delay within each lens/detector combination are measured during a calibration. A calibrating reflector reflects a test signal during the calibration at many frequencies, temperatures and accelerations. Measurements of paths and delays obtained during the calibration are stored, and used to phase compensate subsequent target reflections for coherent processing.

The embolization device has a surface, which may be coated with composition retaining material such as a polymer, bio-polymer or non-polymer based technology that allows sustained release of drug or material from drug eluting occlusive device. For example, an anti-angiogenic composition is coated on the application surface. The embolization device is then inserted in the vessel and embolization is enhanced by the composition.

Abstract: A radar transmitter is at a first location on a moving platform and illuminates a target with a sequence of frequency modulated radar pulses. The frequency modulated pulses are linear frequency modulated, i.e. chirped. The target reflects the frequency modulated radar pulses. A receiving antenna has a difference pattern null and receives the reflections from the target as a main scatterer and an ambiguity of the main scatterer. The sequence of pulses change the start of their frequency modulation (chirp) over a SAR array. The change in start frequency from pulse to pulse allows to shift the range ambiguity so as to align with the delay/Doppler difference pattern null of the antenna. Thus, both the main scatterer as well as the shifted range ambiguity are on the difference pattern null, facilitating their cancellation.

Abstract: A radar antenna has a reflector and maximum gain along its boresight. The reflector has a periphery, typically circular, rectangular or elliptical. A plurality of Global Positioning System (GPS) satellite signal receiving antennas are rigidly, mechanically attached to the reflector near its periphery. The plurality of GPS satellite signal receiving antennas are connected pairwise to a phase comparator for comparing a plurality of first phase differences induced by a first GPS satellite signal received concurrently between the plurality of GPS satellite signal receiving antennas. A Phase comparator measures the phase difference of the signal received at GPS satellite signal receiving antennas pairwise thus performing a differential phase measurement. This differential phase measurement is supplied to a computer for identifying an ambiguous boresight position using the phase differences measured by the phase comparator. The position of the GPS satellites is known with respect to the geo-location of the antenna.

Abstract: A radar system (500) radiates a radar transmit signal, has a radar signal receiver (503) and a canceller (505) for canceling leakage of the transmit signal into the radar signal receiver (503). The canceller (505) comprises a digital waveform generator (528) for generating a first digital signal converted to an analog waveform. The analog waveform is amplified after a fixed delay (534) to generate a first cancellation signal input into a circulator (504). The circulator combines the first cancellation signal with the leakage to generate a first corrected signal. A summer (507) combines the first corrected signal from the circulator with a second cancellation signal to generate a second corrected signal. The second cancellation signal is generated by a digital cancellation filter (526). The digital cancellation filter (526) has as an input the first digital signal from the digital waveform generator (528).
