Abstract The authors deal with the problem of the design and manufacture of a high‐resolution FMCW radar for drone detection and classification. The difficulties of the problem are discrete clutter reduction and spurious phase noise mitigation. The

The paper deals with a problem of noise reduction for drone detection with high range resolution radars. The considered discrete clutter includes land vehicles, birds, etc. This clutter involves in the radar echo signals and could not be rejected by

A range profile (RP) is a vector of reflected powers from a target by the range direction and is used for the purpose of target recognition. In this paper, a problem of formation of RPs is investigated. The well-known difference operator and window-b

The paper deals with a problem of performance evaluation of the range-bearing centroid processing for a surveillance radar. First, we review several techniques for centroid processing that are Moving window estimator, Beam shape centroid estimator, C

In this paper, we investigate the problem of detection of abnormal moving speeds for a coastal surveillance radar. A new definition of normal moving speeds which is based on the historical radar data of maritime targets on the monitoring area is intr

In this paper, a staggered Pulse Repetition Frequency (PRF) coherent integration based on phase/time compensation algorithm in the receiver is proposed. Two staggered PRFs are used to extend blind Doppler frequency. The phase/time compensation algori

We propose a new automatic target recognition (ATR) tool for coastal surveillance pulse-Doppler radars. The novelty of this tool consists of the new features for classification and a new classification algorithm which is performed by combining the pr

An algorithm for 2D-OS-CFAR thresholding in clutter environments is proposed. A sliding window is designed and moved in the considered clutter area. The threshold values for CFAR detection are calculated based on the distribution analysis of the dist
