A General Sequential Delay-Doppler Estimation Scheme for Sub-Nyquist Pulse-Doppler Radar
Shengyao Chen, Feng Xi, Zhong Liu
Sequential estimation of the delay and Doppler parameters for sub-Nyquist radars by analog-to-information conversion (AIC) systems has received wide attention recently. However, th…
