Performance analysis of a dynamic programming track before detect algorithm
LA Johnston, V Krishnamurthy - IEEE Transactions on …, 2002 - ieeexplore.ieee.org
We analyze a dynamic programming (DP)-based track before detect (TBD) algorithm. By using
extreme value theory we obtain explicit expressions for various performance measures of …
