Techniques for homodyne dechirp-on-receive linearly frequency modulated radar
, 2011 This thesis presents work done to extend and improve the operation of homodyne dechirp-on-receive linearly frequency modulated radars. First, an investigation of the effect of common phase errors on the point response function of the radar is ...
