Table 1 Computation complexity of our adaptive reconstruction method
From: Adaptive reconstruction for azimuth signal of multichannel HRWS SAR imaging system
Parameter dimension | Operation | Computation complexity |
|---|---|---|
M, N a , L, K | 1. N | 3·K·M·N a |
| Â | 2. F p | \(K\cdot \left (L\cdot M^{2}+\mathcal {O}\left ({M^{3}}\right)\right)\) |
|  | \({\hat {\boldsymbol {R}}}({F_{b}})\) | L·M2 |
| Â | F p (F b ) | \(\mathcal {O}({M^{3}})\) |
| Â | Total | \(3{KMN}_{a}+K\left (L M^{2}+\mathcal {O}\left ({M^{3}}\right)\right)\) |
