“…In addition to civilian applications, relevant research has also been conducted in the military domain. For instance, based on the estimation of target micro-motion parameters, the identification of warheads has been accomplished, taking into account the different forms of target micro-motions (Gao et al, 2010;Han, Feng, 2020;Zhang et al, 2023).…”

Motion characterization, including Doppler and micro-Doppler, is crucial for the detection and identification of high-speed underwater targets. Under high-frequency and short-range conditions, underwater targets cannot be simply regarded as single highlight targets as they exhibit a complex structure with multiple scattering centers accompanied by distinct micro-motions. To address this multi-highlight and multi-micro-motion scenario, a model is proposed to characterize the motion features of underwater targets. Firstly, a mathematical model is established to represent the micro-Doppler features based on the single-highlight model. Subsequently, considering the overlap of multiple highlight echoes caused by the high-speed translation of the target and the long pulse detection signal, precise representation is achieved by setting motion positions and calculating time delays within the model. The results represent the echoes of moving targets with multiple highlights and micromotions. Finally, a time-frequency analysis method is employed to extract motion features and estimate target parameters, thereby validating the accuracy and effectiveness of the proposed model. This research provides a theoretical foundation for the modeling of underwater moving targets.

“…N OWADAYS, one can find aerial vehicles with extreme maneuverability, such as drones [1], [2], jets or aircrafts [3], [4], rockets [5], and warheads [6]. Giving unique abilities to flying targets is particularly important on the battlefield as it allows such targets to avoid attacks by rapid acceleration and changes in flight direction.…”

Flying targets are becoming increasingly maneuverable, contributing to the growing problem of their detection with active and passive radars. Rapid acceleration causes blurring of the target echo on the range-Doppler (RD) map, which reduces the signal-to-noise ratio (SNR) in a given range and velocity cell. This paper proposes a novel, non-parametric approach to quickly and efficiently estimating target acceleration on the RD map. In the paper, a universal signal model for an active frequency-modulated continuous wave radar and a passive radar is introduced. Based on this model, an estimation algorithm has been developed that can be applied to both active and passive radars. Compared to the method known from the literature, the proposed solution is much faster (even more than 100 times) while maintaining numerical stability and allowing for the estimation of acceleration of many targets to be performed simultaneously. The proposed method was supported by simulation tests and signals from real-life active and passive radars observing a jet fighter and a drone. The obtained outcomes show that the proposed technique can be successfully used for autonomous real-time systems that detect and estimate the parameters of maneuvering vehicles.
