The concurrent imaging mode using TerraSAR-X is a technique that allows the acquisition of two images in a single flyover. It brings high versatility and can double the image output rate. These benefits are of great interest as there is a long revisit time for spaceborne SAR systems. One of the main drawbacks is the use of high pulse repetition frequencies (PRFs), which causes ambiguity issues and timing limitations. Therefore, knowing and improving the quality of the imaging mode is desired. This paper presents a quantitative analysis of its global availability. Moreover, a technique named multiple pulse repetition intervals (PRIs) is proposed to improve the coverage of the imaging mode while maintaining its ambiguity performance. Further simulations are presented, confirming the benefits of the technique, culminating in a vast global availability for the concurrent mode.
