Точність Вимірювання Кутових Координат Аеродинамічних Об’єктів В Умовах Тропосферної Рефракції

Abstract: Трикоординатні радіолокатори є найбільш універсальними з технічної точки зору засобами визначення просторового положення аеродинамічних об’єктів та забезпечення їх подальшого супроводження. При цьому їх функціонування часто здійснюється у складних метеорологічних умовах, зокрема в умовах тропосферної рефракції. Вимірювання кутових координат існуючими трикоординатними радіолокаторами здійснюється в основному без врахування динаміки зміни поточного стану тропосфери Землі, тому стаття присвячена досліджен… Show more

“…In [10], relations were obtained that take into account the transformation of spectral and temporal representations of single and bundle radio signals reflected from an accelerating object. The practical application of this transformation in assessing the quality of detection of moving objects is considered in [11], which takes into account the differences in changes in the time scale of the carrier oscillations and their complex envelope. The results of these works should also be used to solve the frequency resolution problem.…”
