17675 最后使用一种添加部分经过转换网络转换的数据进行训练的方法。 Finally, a training method is used to add a part of data transformed by the transformationnetwork.
17676 总的mAP值与原算法相比提升了3%，并且分割边界精确度和鲁棒性都有一定提高。 Compared with the original algorithm, the total mAP value is improved by 3%, and the accuracy androbustness of segmentation boundary are improved to some extent.
17677 广播式自动相关监视(ADS-B)作为一种新的监视技术正受到国际民用航空组织(ICAO)的大力推广。 The Automatic Dependent Surveillance-Broadcast (ADS-B), as a new surveillance technology, is being vigorously promoted by International Civil Aviation Organization (ICAO).
17678 然而，由于ADS-B信号传输具有随机性，多条信号交织问题不可避免。 However, overlapping among multiple signals is inevitable because of the randomness of ADS-B signal transmission.
17679 该文提出一种改进的单天线投影算法(PASA)，利用单通道分离交织信号。 An improved ProjectAlgorithm Single Antenna (PASA) algorithm which separates the overlapping signals with one single channel isproposed.
17680 首先对单通道接收到的数据提出一种新的矩阵重构方式，从而降低两条信号之间的相对时延和频偏要求；然后利用投影算法分离交织信号。 Firstly, a new matrix reconstruction method for the data that received by single channel is proposedto decrease the requirement of relative time delay and frequency difference between two ADS-B signals, andthen the overlapping signals can be separated by utilizing the projection algorithm.
17681 仿真实验结果验证了该算法的有效性。 The effectiveness of thealgorithm is verified by simulation experiments.
17682 由于天基雷达覆盖范围广，大量强离散杂波(小型岛礁、陆地铁塔等)会从天线旁瓣进入雷达系统，其多普勒特征与目标相同，极易造成虚警。 On account of the large coverage of space based radar, a lot of discrete strong side-lobe clutter, whichshares familiar Doppler feature with the real moving targets, can be received by the radar system and henceresults in false alarms.
17683 针对以上问题，该文提出基于空时导向约束的天基雷达离散旁瓣杂波判别方法， For this problem, a discrete side-lobe clutter recognition method using space-timesteering vectors for space based radar system is proposed.
17684 该方法首先选取空时自适应处理(STAP)杂波抑制后检测到的潜在“目标”(包含真实目标与离散旁瓣杂波)距离多普勒单元及其附近单元； In this method, the “Suspected targets”, includingboth the real moving targets and discrete side-lobe clutter, are detected after suppressing clutter by employingthe Space-Time Adaptive Processing (STAP). The range-Doppler cells where “suspected targets” located inor around are selected.
