The principles of medium PRF (pulse-repetition-frequency) radar and the specific requirements of a radar system place restrictions on the choice of these PRFs. The author documents typical constraints placed on a pulse-Doppler search-mode PRF set. He sets forth an efficient approach for selecting a near-optimum set.

presented how the exact Pareto optimal (PO) set can be determined by means of exhaustive search. In this paper, they improve the mathematical model of the waveform optimisation problem by altering the way in which one of the objective functions is

This paper proposes a novel pulse repetition frequency(PRF) selection scheme in medium PRF pulsed-Doppler radars. The optimization is driven by the requirement not only to minimize the blind zone in the range and velocity space but also to ensure the full decodability of the true range and Doppler frequency.

This paper proposes a new method to select optimal pulse repetition frequency (PRF) sets for use in tracking mode of medium PRF airborne pulsed-Doppler radar by applying different optimal PRF set to different engagement scenarios and target positions.

In multiple pulse repetition frequencies (PRFs) radars, the PRF set is used to resolve the ambiguities in both range and Doppler frequency. In this paper, a novel PRF selection scheme is proposed. The optimization is driven by the requirement to maximize the decodable velocity space for low PRF applications.

The selection of an optimal PRF set is constrained by radar system characteristics, application requirements, ghost minimization, and sampling rates. The paper presents an efficient combinatorial approach to calculate PRF set quality, addressing these constraints and discussing their implications to enhance radar performance.

The PRF set selection is complex, restricted by the particular radar system and its intended use. After briefly discussing constraints, some results concerning ghost minimisation, and the linearity of clear region probabilities, an efficient method is presented for calculating PRF set quality.
