This paper presents a new radar system that combines any number and any kind of radar signals and transmits them simultaneously, thereby obtaining all the advantages of each of the radar waveforms used. This new system is based on a low-rate coded time compression overlap-add (TC-OLA) technique, and allows radar designers to address the challenge of having many features, such as high-time resolution, high-Doppler tolerance, low-sidelobe level, and low probability of intercept (LPI), in a single waveform. Since different types of radar waveforms usually offer different features, the new system allows the designers to obtain optimality via pluralism. The performance evaluation of the new radar system shows its superiority when examined under noise and heavy-tailed clutter background over the classical radar system and other methods of combination by operating on $N$ -radar signals simultaneously, making use of features from each waveform, canceling the Doppler from a Doppler-intolerant signal, and adding an extra processing gain to the proposed system.

使用时间压缩重叠相加组合多个雷达波形的新框架

本文提出了一种新的雷达系统，该系统可以组合任意数量和任意类型的雷达信号并同时传输它们，从而获得所使用的每种雷达波形的所有优点。这种新系统基于低速率编码时间压缩重叠相加 (TC-OLA) 技术，使雷达设计人员能够应对具有许多功能的挑战，例如高时间分辨率、高多普勒容差、低单波形中的旁瓣电平和低截获概率 (LPI)。由于不同类型的雷达波形通常具有不同的特性，因此新系统允许设计人员通过多元化获得最优性。$N$ -同时雷达信号，利用每个波形的特征，从多普勒不容忍信号中消除多普勒，并为建议的系统增加额外的处理增益。
