Fast orthonormal past algorithm
WebSep 1, 2010 · Simulation results show that the robust KFVNM-based subspace tracking algorithm has a better performance than the PAST algorithm for tracking fast-varying subspace and in an impulsive noise environment. The conventional projection approximation subspace tracking (PAST) algorithm is based on the recursive least-squares algorithm, … WebWe propose a subspace-tracking-based space-time adaptive processing technique for airborne radar applications. By applying a modified approximated power iteration subspace tracing algorithm, the principal subspace in which the clutter-plus-interference reside is estimated. Therefore, the moving targets are detected by projecting the data on the …
