According to the characteristics of underwater high-speed moving target, a single scale correlative processing fast algorithm using wideband Pros and Cons frequency modulation HFM signal was advanced. Based on the analysis on the algorithm's parameters estimation deviation variance, a scale approaching iterative algorithm was brought forward. The computer simulation of the two algorithms was accomplished...
A new design method of wideband beam-former with constant beam-width is proposed: within every frequency bin, assume all weighting sequences of beams oriented to different directions are the same, and then it can be deduced that the sequences in all sub-bands have the same spectrum, but a scale relationship is satisfied on the frequency axes. The scale is equal to the ratio of the central frequency...
