Abstract

This paper presents a study of how the Analogue to Digital Converter (ADC) sampling rate in a digital radar can be reduced - without reduction in waveform bandwidth - through the use of Compressed Sampling (CS). Real radar data is used to show that through use of chirp or Gabor dictionaries and Basis Pursuit (BP) the ADC sampling frequency can be reduced by a factor of 128, to under 1 mega sample per second, while the waveform bandwidth remains 40 MHz. The error on the reconstructed fast-time samples is small enough that accurate range-profiles and range-frequency surfaces can be produced. © 2010 IEEE.
