Buku ini menyajikan formulasi analitis terperinci untuk RCS dari array dipol linier yang diumpankan paralel dengan adanya kopling timbal balik. Penampang lintang radar (RCS) suatu objek menunjukkan sifat hamburan elektromagnetik (EM) untuk gelombang insiden tertentu. Analisis medan hamburan sangat penting dalam bidang militer dan pertahanan, terutama saat merancang platform yang rendah teramati…
Dalam buku ini, RCS dari array dipol linier dan planar yang diumpankan paralel diturunkan menggunakan metode perkiraan. Perambatan sinyal dalam sistem array bertahap menentukan penampang lintang radar (RCS) dari array bertahap. Koefisien refleksi dan transmisi untuk sinyal pada berbagai tingkat sistem array hamburan bertahap bergantung pada ketidaksesuaian impedansi dan parameter desain. Selain…
This book presents a comprehensive review of plasma-based stealth, covering the basics, methods, parametric analysis, and challenges towards the realization of the idea. The concealment of aircraft from radar sources, or stealth, is achieved through shaping, radar absorbing coatings, engineered materials, or plasma, etc. Plasma-based stealth is a radar cross section (RCS) reduction technique as…
In this book, a modified improved LMS algorithm is employed for weight adaptation of dipole array for the generation of beam pattern in multiple signal environments. In phased arrays, the generation of adapted pattern according to the signal scenario requires an efficient adaptive algorithm. The antenna array is expected to maintain sufficient gain towards each of the desired source while at th…
This book focuses on determination of scattering of parallel-fed planar dipole arrays in terms of reflection and transmission coefficients at different levels of the array system. In aerospace vehicles, the phased arrays are often in planar configuration. The radar cross section (RCS) of the vehicle is mainly due to its structure and the antennas mounted over it. There can be situation when the…
This book focuses on high-gain antennas in the terahertz spectrum and their optimization. The terahertz spectrum is an unallocated EM spectrum, which is being explored for a number of applications, especially to meet increasing demands of high data rates for wireless space communications. Space communication systems using the terahertz spectrum can resolve the problems of limited bandwidth of p…
