Hierarchical Track-Before-Detect Algorithm for Tracking of Amplitude Modulated Signals

In the paper Track–Before–Detect (TBD) algorithm for tracking a low–signal objects with amplitude modulated signal is proposed. Direct application of TBD algorithms is not sufficient for such case due to accumulative approach. This signal has a zero mean value and cannot be processed directly. The proposed algorithm is based on applications of two different TBD algorithms. The first is the directional IIR filter that works as a velocity filter as a part of the noncoherent demodulator. The second TBD algorithm is the recurrent Spatio–Temporal TBD that support trajectory switching using Markov’s matrix. Numerical experiments (Monte Carlo tests) for point target are used for verification of the proposed solution.
