Abstract
Small Boat Detection Using OFDM Radar
Highlights
Detection of a small boat using radar is of significant importance for security and surveillance
Simulation results to validate the proposed method of estimating Orthogonal frequency division multiplexing (OFDM) radar return data and performance analysis of the proposed detector for estimated and simulated data are described in detail
We proposed a method to estimate the OFDM radar return data using CSIR recorded radar return data for stepped frequency (SF) waveform
Summary
Detection of a small boat using radar is of significant importance for security and surveillance. For small boat detection in a high clutter environment, many algorithms [3,4,5,6,7,8,9] have been proposed in the literature. In [5], a detection algorithm with constant false alarm rate is derived, with performance analysis over both the simulated and the real sea data. To the best of authors’ knowledge, the merits of OFDM waveform have not yet been verified and validated using real radar return from sea clutter. Major contributions of this work are as follows: We propose a technique for the detection of small boat by utilizing an estimated radar return for the OFDM waveform. C and R denotes the set of complex and real numbers, respectively. diag, tr and R are respectively the diagonal, trace, and rank operation over a matrix
