2020年9月1日 · To achieve this goal, we propose variable step size multi-PRF and multi-frame (or scan) TBD (MP-MF-TBD) algorithm. Specifically, by incorporating the ambiguity factors related to both the range and velocity ambiguities, MP-MF-TBD first accomplishes the target SNR integration directly using multiple ambiguous measurement frames.

2022年3月11日 · This article considers the detection and tracking of weak targets in multiple pulse repetition frequency (multi-PRF) radars using the track-before-detect (TBD) technique.

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 nov

An algorithm for velocity ambiguity resolution in coherent pulsed Doppler radar using multiple pulse repetition frequencies (PRF) is presented. It relies on the choice of particular values for the PRFs.

2019年9月25日 · In this paper we proposed an MF-TBD algorithm for multiple PRF radar system, i.e. classical ambiguity resolution TBD (CAR-TBD) first resolves ambiguities by means of a robust CRT, and then MF-TBD is applied for further tracking.

To achieve this goal, we propose variable step size multi-PRF and multi-frame (or scan) TBD (MP-MF-TBD) algorithm. Specifically, by incorporating the ambiguity factors related to both the range and velocity ambiguities, MP-MF-TBD first accomplishes the target SNR integration directly using multiple ambiguous measurement frames.

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.

2020年5月1日 · This paper considers the detection and tracking of dim targets for multiple pulse repetition frequency (PRF) pulsed Doppler radar systems through the use of multi-frame track-before-detect (TBD...

Abstract: This paper presents an approach to the improvement of the range ambiguity resolution performance by making use of an extended Chinese Remainder Theorem (CRT), which is valid for moduli non-mutually prime.

computer model which simulates a Multiple High PRF Pulse Doppler radar has been developed. The model has the capability of computing the system parameters for Post Detection Processing necessary to achieve given desired probabilities of detection and false alarm.
