摘要翻译：
研究了基于$TV$-最小化的到达方向估计问题。与以前在这个方向上只考虑某些天线布局设计的工作相反，我们考虑一般天线几何形状。应用软恢复框架，我们可以推导出对某一到达方向进行近似恢复的理论保证。我们讨论了恢复保证对几个具体天线设计的影响。此外，还进行了数值模拟，以支持理论部分的发现。

英文摘要：
The estimation of direction of arrivals with help of $TV$-minimization is studied. Contrary to prior work in this direction, which has only considered certain antenna placement designs, we consider general antenna geometries. Applying the soft-recovery framework, we are able to derive a theoretic guarantee for a certain direction of arrival to be approximately recovered. We discuss the impact of the recovery guarantee for a few concrete antenna designs. Additionally, numerical simulations supporting the findings of the theoretical part are performed.
