| Abstract: | Search and rescue satellite-aided tracking (SARSAT) has certain shortcomings which could possibly be ameliorated by employing a more extensive signal processing strategy. The approach proposed is based on partially compensating for the Doppler shift, which then permits the data processing windows to be increased significantly. Incorporating a ranking technique with the conventional fast Fourier transform (FFT) processor and implementing an autoregressive moving-average estimator provides an optimal strategy that maximizes the probability of detecting the emergency signals |
