The Aliasing Analysis and Resolution Calculation of Tilting Sampling System

The tilting sampling which rotates the single array with a degree and reduces the sampling distance can get a better resolution with less hardware cost.This paper introduces titling model and the supertilting model sampling.Then the resolution under different sampling systems is discussed.Based on reciprocal cell in the frequency domain,the relation model of aliasing and tilting sampling is built.The effective resolution based optimal reciprocal cell is calculated to get the set of spectrum with less aliasing and noise.Experimental results indicate that tilting sampling mode with optimal reciprocal cell improves the resolution effectively.
