Bistatic synthetic aperture radar (BiSAR) and multistatic (MuSAR) systems with a separated transmitter and receiver have been widely used for remote sensing. However, frequency deviation among different oscillators will cause a modulated phase error on the echo signal. Therefore, phase synchronization is one of the most critical problems to be addressed in BiSAR/MuSAR systems. In this article, we review synchronization techniques, which include synchronization by direct signal, synchronization by synchronization module, and synchronization by autonomous estimation. Furthermore, the future development of synchronization technology is prospected.

Machine learning algorithms have demonstrated impressive results for land cover mapping from hyperspectral data. To enhance generalization capabilities of statistical models, active learning (AL) methods guide the annotation of the training data set by querying the most informative samples. The training of the classifier can then be performed on an optimal training data set. We bring under the same framework uncertainty, representativeness, and performance-based AL techniques; conduct a benchmark on state-of-the-art methods and release a toolbox (https://github.com/Romain3Ch216/AL4EO) to allow experimentation with these approaches. The experiments are conducted on various data sets: a toy data set, classic hyperspectral benchmark data sets, and a complex hyperspectral scene. We evaluate the methods with usual accuracy metrics as well as complementary metrics, which allow us to provide guidelines when choosing a relevant AL strategy in a real use case.

Remote sensing-based forest investigation and monitoring have become more affordable and applicable in the past few decades. The current bottleneck limiting practical use of the vast volume of remote sensing data lies in the lack of affordable, reliable, and detailed field references, which are required for necessary calibrations of satellite and aerial data and calibrations of relevant allometric models. Conventional field investigations are mostly limited to a small scale, using a small quantity of observations. Rapid development in close-range remote sensing has been witnessed during the past two decades, i.e., in the constant decrease of the costs, size, and weight of sensors; steady improvements in the availability, mobility, and reliability of platforms; and progress in computational capacity and data science. These advances have paved the way for turning conventional expensive and inefficient manual forest in situ data collections into affordable and efficient autonomous observations.

The oceans are an important component of Earth’s system and play a crucial role in climate change through the coupled atmosphere–ocean process. Observations are fundamental for studying and understanding the oceans. While in situ measurements are limited, satellites can remotely monitor oceans continuously for extended periods, with broad spatial coverages. These sustained in situ and remotely sensed observations are available for longer time periods; however, the later are limited to the surface ocean. Owing to the unavailability of subsurface observations, the limited studies could focus on understanding subsurface oceanic processes [e.g., subsurface flows and eddies, internal waves (IWs) and tides, undercurrents, and so on] and conducting comprehensive studies of the oceans, such as the recent warming of oceans.
