A Function of Time , Frequency , Lag , and Doppler yJe
In signal processing, four functions of one variable are commonly used. They are the signal in time, the spectrum, the auto-correlation function of the signal, and the auto-correlation function of the spectrum. The variables of these functions are denoted, respectively, as time, frequency, lag, and doppler. In time-frequency analysis, these functions of one variable are extended to quadratic fu...

15 صفحه اولFpga Realization of Time-frequency Distribution with Complex-lag Argument
Due to its ability to provide good concentration in the time-frequency plane, the fourth order complex-lag time-frequency distribution has been used for the analysis of signals with highly non-stationary instantaneous frequency. In order to make it available for practical applications, an architecture for realization of this distribution is proposed. The FPGA implementation is provided as well....
متن کامل3-D Time/Frequency-Range-Doppler
In this paper, we introduce the concept of 3-D radar signatures in a slow time-range-Doppler, fast timerange-Doppler and frequency-range-Doppler. Then, we describe how to utilize 3-D time or frequency-rangeDoppler signatures to extract information for detecting, relocating and re-focusing moving targets. Finally, we use AN/APY-6 X-band radar data for the demonstration of ground moving target de...
