| 中文摘要: |
| 针对单线阵进行弱目标跟踪时容易受到强目标影响的问题，将三元组线列阵进行分裂波束定向，可提高对弱目标的方位跟踪能力。通过将三元组线列阵等分为两个三元组子阵，对两个三元组子阵分别进行心形波束形成，利用各自心形波束输出进行分裂波束处理得到目标方位。与常规单线阵分裂波束目标跟踪方法相比，该方法不但能给出跟踪目标的左右舷信息，同时提高了不同舷侧存在多目标时的目标跟踪能力。对海试数据的实际处理结果表明，三元组线列阵分裂波束定向时提高了对多目标的方位跟踪能力。 |
| 英文摘要: |
| A split-beam bearing track method of triplet linear array is proposed in the paper, which can be used to improve the the weak target tracking performance of a single linear array. The triplet linear array is equally divided into two same sub-triplet linear arrays, then the heart-shaped beamforming is carried out respectively for the two sub-triplet linear arrays, and the target azimuth is obtained by using split-beam processing with the respective heart-shaped beam outputs. This method can not only give the target's port-starboard information, but also improve the performance of tracking target when there are many targets on different sides. Results of sea trial show that the proposed method has an excellent multi-target tracking ability. |
