Novel method estimates Doppler frequencies in PRI-staggered radar systems, indicating improved countermeasure capabilities.
The utilisation of staggered pulse repetition intervals (PRIs) in pulse‐Doppler (PD) radar systems is instrumental in expanding the unambiguous Doppler interval, which is traditionally confined by the constraints of uniform PRIs, and in enhancing the electronic countermeasures capabilities of the radar. However, the presence of high Doppler sidelobes emerges as a principal impediment to the practical deployment of such systems. In this paper, we introduce a novel approach to accurately estimate the Doppler frequencies of targets in PRI‐staggered radar systems, which integrates gradient descent and orthogonal matching pursuit algorithms to effectively reconstruct the Doppler profiles of targets with arbitrary velocities. The simulation results demonstrate the method’s effectiveness and robustness, indicating its promising suitability for practical application within PD radar systems.
