Abstract

A compressive imaging based APT (CI-APT) system is studied for FSO communication. Linear combinations of object pixels, referred to as features, are measured. Then reconstructed objects are used for target locating. Because it is implementation friendly, Hadamard projection is employed for CI-APT. Spatial domain andWavelet domain OMP methods are studied for signal reconstruction. To demonstrate the idea, we use 64 randomly selected Hadamard features to locate a 3 × 3 target in a 256 × 256 object. The averaged location error is less than 2 pixels.
