| Popis: |
The direct path signal, strong multi-path and strong moving target echoes can mask the weak target in passive coherent location (PCL) radar systems. The classical normalized least-mean squares (NLMS) algorithm is widely used in cancelling the direct path and multi-path interferences in PCL radar systems, which cannot suppress the stationary ground clutter and the strong moving target echoes simultaneously. An improved NLMS algorithm, called range-Doppler NLMS (RDNLMS), is proposed for cancelling the interferences with different delays (denoting the range information) and Doppler frequencies in PCL radar systems utilizing the Chinese digital television terrestrial broadcasting (DTTB) transmissions. The validity of the algorithm is verified by the simulative results. |
