雷达系统的理论和设计一直占主导地位
概率论与统计,信息理论,信号处理和控制
然而,类似的编码译码的属性之间存在的视觉
BIAM和雷达已经黯然忽视的m所有雷达系统(For over six decades, the theory and design of radar systems have been dominated
by probability theory and statistics, information theory, signal processing and control
However, the similar encoding-decoding property that exists between the visual
biam and radar has been sadly overlooked m all radar systems)
