Table 1 Complex multiplication amount of different methods
From: A coherent accumulation detection method based on SA-DPT for highly manoeuvring targets
Methods | Computational complexity |
|---|---|
MLE | \(O(kNM^{2} \log_{2} N)\) |
KT | \(O(NM^{2} ) + O(k^{2} NM\log_{2} M)\) |
the direct DPT | \(O(NM\log_{2} MN)\) |
Proposed method | \(O(k^{\prime}NM\log_{2} MN)\) |
