WebbThe zero-Doppler cut of the ambiguity function depicts the matched filter response of a target when the target is stationary. From the plot, one can see that the first null … WebbIntroduction. Radar systems use matched filters in the receiver chain to improve signal-to-noise ratio (SNR). Matched filters are time-reversed and conjugated versions of the …

WebbThe goal of range-and-velocity ambiguity mitigation is to reduce obscuration (“purple haze”) and Doppler velocity errors. Solutions include implementation of the Staggered PRT (SPRT) algorithm, optimization of the existing phase coding (SZ-2) algorithm, and the design of scanning strategies that exploit both. its a good day to have a good day gif
