Two-dimensional harmonic retrieval and its time-domain analysis technique
Xian‐Da Zhang · IEEE Transactions on Information Theory · 1991
The two-dimensional harmonic retrieval is examined in theory by confirming that the 2-D sinusoids in white noise are modeled as a special 2-D autoregressive moving average (ARMA) process whose AR parameters are identical to the MA ones. A new analysis technique for resolving 2-D sinusoids in white noise is proposed.>
