Phase and pattern calibration of the Jicamarca Radio Observatory radar using satellites
(Royal Astronomical Society, 2014-12-08)
The Jicamarca Radio Observatory (JRO) main 50-MHz array antenna radar system with multiple receivers is being used to study meteors via two interferometric receiving modes. One of the major challenges in these studies is ...
Cálculo de coeficientes de arrasto para satélites artificiais
(Universidade Estadual Paulista (Unesp), 2001)
Devido à sua dependência a um grande número de parâmetros de difícil determinação, o cálculo de coeficiente de arrasto para satélites artificiais torna-se extremamente complexo. Teorias, como as desenvolvidas por Schamberg ...
