1 quadratic phase kernel
квадратичное фазовое ядро (имеет вид ехр[-i2pi (at + btt)] и представляет собой первое обобщение традиционного линейного фазового ядра за счёт учёта второго (квадратичного) члена разложения фазовой функции phi(t) в ряд Тейлора по степеням аргумента t; используется при спектральном преобразовании m с линейной частотной функцией); ср. conventional Fourier kernel, linear phase kernelАнгло-русский словарь промышленной и научной лексики > quadratic phase kernel
