Phased array radar systems

Phased array systems provide a number of features which make them particularly suitable for long range, high target density, radar applications such as satellite tracking and space surveillance. These include long-range detection capability, high transmitted power, inertialess electronic beam steering, multiple receiving-beam capability, high reliability and extreme flexibility. Basic principles of phased array system operation are presented and a 90-element linear array feasibility model and a large scale u.h.f. planar array are described. Several potential applications of phased array systems for space surveillance are discussed.
