| 摘要 |
The invention relates to a radar apparatus (1, 2, 3) provided with a doppler filterbank (4) and fast thresholds (5.i), for writing per pulse a range-doppler matrix in range-doppler memory (6) and the background level in background memory (7). By unfolding the range-doppler matrices and combining the unfolded range-doppler matrices for all the pulses in a burst in combination means (10), an incoherent combination of the pulses is obtained before an actual detection takes place. This cluster before detect scheme increases the detection probability for weak echoes, without increasing the false alarm rate. <IMAGE> |
