Abstract: The present invention relates to a method for processing received radar returns of a radiated wide-band arbitrary waveform in a wide-band radar processing system using spectral processing. The method is characterized by the steps of: undersampling said received wide-band radar returns by using a first sampling rate to obtain an undersampled digital wide-band radar waveform; performing spectral processing on the power spectrum of said undersampled digital wide-band radar waveform in order to obtain a discrete ripple frequency power spectrum of said undersampled digital wide-band radar waveform; and locating, in said discrete ripple frequency power spectrum of said undersampled digital wide-band radar waveform, ripple frequencies indicating radar targets. The present invention also relates to a radar receiver, a digital wide-band radar processing system and a computer program product.

Abstract: The invention relates to an electro-optical distance measuring method wherein frequency-modulated optical radiation is emitted onto at least one target to be measured. Once the radiation back-scattered to the target is received, the chirp of radiation is modeled by means of a phase function Φ(t) having parameters cj, thereby making description of the deviation of the chirp from the linear profile possible. The parameters used for description are at least partially determined from measurements or are coestimated during numerical signal processing.

Abstract: Digital beamfonning is provided for use with electronically scanned radar. In an aspect, the present invention provides enhanced sensitivity, wide angle or field of view (FOV) coverage with narrow beams, minimized number of receivers, reduced sidelobes, eliminated grating lobes and beam compensation for target motion. In an aspect, the present invention employs a uniform overlapped subarray feed network (420), a time multiplexed switch matrix (424), and a restructured digital signal processor (430). Antenna channels share a receiver (406), rather than maintain a dedicated receiver for each antenna element, as in conventional systems. In an aspect, Doppler/frequency filtering (432) is performed on each antenna element or subarray output prior to digital beamforming (436). Further, Doppler compensation (434) is employed following Doppler/frequency filtering (432), followed by digital beamforming (436).

Abstract: In an FM-CW radar system, a frequency modulating wave output from said modulating signal generator has a frequency variation skew with respect to a time axis (modulation skew), and the radar system includes a means for varying the modulation skew by controlling the modulation frequency amplitude or modulation period of the modulating signal. The radar system further includes a means for discriminating a signal component varying in response to the variation of the modulation skew, thereby discriminating a signal related to a target object from other signals. In the case of an FM-CW radar system that performs transmission and/or reception by time division ON-OFF control, the radar system includes a means for discriminating a signal which, when the frequency used to perform the ON-OFF control is varied, varies in response to the variation of the frequency, thereby discriminating a signal related to a target object from other signals.
