Radar detection of targets in sea clutter modelled by compound K-distribution is examined from a statistical detection viewpoint by Monte Carlo simulations. The detection performance of Cell Averaging Constant False Alarm Rate (CA-CFAR) is compared with the performance of fixed threshold detection. The performance evaluations are quantified by CFAR loss.(More)
In this paper, we work on the electromagnetic target recognition problem based on the scattered field measurements. These measurements were obtained both in frequency and time domains by using two 0.8-12 GHz horn antennas in bistatic position and HP8720D vector network analyzer. First, the theory of electromagnetic scattering from a target and singularity(More)
An active antenna array design and simulation of this design with a microwave circuit simulator are presented. This active antenna array is a TV receive only (TVRO) antenna operating at 10 GHz. It is a 8/spl times/4 array of rectangular microstrip patch antennas. Eight low noise pHEMTs are placed in the antenna. Passive antenna characteristics are usually(More)
This paper is a work about the importance of wide frequency deviation, Deltaf, in linear FMCW radar applications and the design and measurement results of the antenna thought to be suitable for these applications. First, working principle of linear FMCW radar is briefly told. Afterwards, it will be mentioned about the benefits of choosing high frequency(More)
Radar target detection of targets in sea clutter modelled by compound K-distribution is examined from a statistical viewpoint by Monte Carlo simulations. The target detection is processed by Cell Averaging Constant False Alarm Rate (CA-CFAR) processor and the performance evaluations are quantified by CFAR loss. Curves for CFAR loss versus the spatial(More)
