A SAR Target Recognition Method via Combination of Multilevel Deep Features

Algorithm 1

Clustering algorithm for deep features.

	Step 1: Set the correlation threshold and initialize t = 1;
	Step 2: Set as the initial cluster center, record , and execute the following cycle judgment
	for j = {1, 2, …, N}
	if
	end
	end
	Step 3: Get a set of features
	Step 4: Update , t = t + 1; Repeat steps 1∼3 until all the features are clustered.
