2343 再次，针对地面移动中继非完整约束导致的对 UAV 空基平台分簇覆盖的拓展性不足，研究了多个地面移动中继的联合运动策略，以应对部分地面移动中继失效或因降低移动物联网的成本而出现地面移动中继数量减少的状况。 Third, joint motion strategy for multiple ground mo-bile relays is researched to improve the expansibility of ground mobile relays for covering the UAV clusters, which is causingby nonholonomic constraints. It is useful to deal with the ground mobile relays failure or costs reduce.
2344 最后，通过实验验证了本文所提方法的有效性。 Finally, the effective-ness of the proposed method is verified through experiments.
2345 主瓣干扰对抗一直以来是雷达领域的难题之一，给雷达的探测、跟踪和识别带来了严重威胁。 The suppression of mainlobe jamming (MLJ)is a hard task and an open problem in the radar field, and it brings a big challenge for radar target detection, tracking, and identification.
2346 对此，本文提出了一种主瓣干扰环境下的雷达目标参数“同维”稀疏估计方法，可有效抑制主瓣干扰并估计目标距离、角度参数。 Hence, we propose a“same dimension”sparse estimation method for radar target parameter in MLJ. The proposed method can effectively suppress the MLJ and simultane-ously estimate the target range and angle.
2347 所提方法首先对接收信号进行阻塞矩阵预处理，可在抑制主瓣干扰的同时保持目标回波在各阵元之间的相位关系，即保留了目标的角度信息; Precisely, the block matrix preprocessing (BMP)algorithm is adopted to suppressthe MLJ, and the target angle information can be hold on.
2348 然后对预处理后的数据进行空域波束合成并脉压，可估计目标的距离参数信息; Then the target range is estimated effectively through the beam-forming and pulse compression.
2349 最后，根据得到的目标距离估计，截取预处理数据中目标附近的数据，并对其进行稀疏恢复估计目标角度参数。 According to the target range estimation result, the preprocessed data should be interceptedas training samples for the target angle estimation.
2350 所提方法即可应用于面阵，也可应用于线阵， The proposed method can be applied for linear array and planar array.
2351 其优势在于可以在空域任何一维上抑制主瓣干扰，并同时估计目标在空域两维上的角度。尤其是当目标与干扰的某一维空域角度相同时，所提方法仍然可以同时估计目标的方位、俯仰角。 It is worth pointing out that the proposed method can effectively estimate the target azimuth and elevation simultaneously when the target azimuth (or elevation)equals to the jamming azimuth (or elevation).
2352 脉压被广泛用于雷达系统以提高系统分辨率。 As a wide spread technology in radar systems, pulse compression is used to improve the radar resolution.
