Principles of Space-Time Adaptive Processing

In Tables 15.1 and 15.3 the numbers of floating point operations (complex multiplications) for the various parts of the adaptive clutter filter and target doppler match are given. Table 15.1 summarises those operations not strictly connected with the range sampling frequency. They are therefore called 'slow' operations.
| Method | Section | Adaptaion | Filter calculation |
|---|---|---|---|
| OAP* | 4.2.1 | 2( N 3 M 2)* | 8 N 3 M |
| AEP*** | 5.2 | 2( N + M) 3 + 2( N + M) M | ( N + M) 3 + M ( N + M) 2 |
| SAS* | 6.2.1 | 2( K 3 M 2) | 8 K 3 M |
| ASFF* | 7.1.3 | 2( K 3 L 2) | 8 K 3 L |
| ACP | 5.3 | 2( N + M) 3 + 2( N + M) M | ( N + M) 3 + M ( N + M) 2 |
| ASEP | 9.3 | 2( KL 3 + 2 M ( KL) 2 | ( KL) |
