“…The "track before detect" algorithm is a temporal based algorithm which uses multiple frames to incorporate temporal as well as spatial information. A lot of techniques and algorithms was developed within this concept of processing as 3-D matched filtering [8,9], Velocity filter banks [10,11], multistage IIR filter [12,13], Temporal Profile Based detection [14], Temporal filters [15,16], triple temporal filter (TTF) [17], bilateral TTF [18], dynamic programming [19,20], sequential detection [21], parallel spatial and temporal filtering [4,22] and Probabilistic data association (PDA) [23], etc.…”
