高频地波雷达回波信号二维傅里叶变换仿真处理，通过该变换可以得到海上目标的速度和距离信息。-HF ground wave radar echo simulation of two-dimensional Fourier transform processing, the adoption of the sea can transform the speed and distance from goal information.

使用维纳分布进行瞬时频率估计用来校正电离层非线性相位污染带来的频带展宽-High-frequency (HF) sky-wave radar signals propagate to and from the target by means of the ionosphere. The difficulty in obtaining very narrow beamwidths at HF, and the long ranges involved, mean that the

一个VC对话框写的K-J公式计算小程序，能够预测炸药的爆速和爆压。 1、基于CaHbOcNd类炸药，要求输入碳原子数a，氢原子数b，氧原子数c，氮原子数d，炸药的标准生成焓Hf，炸药密度ρ六项数据来计算爆速与爆压。 2、在用户输入界面附有说明：本公式适用于CaHbOcNd类单质炸药，在计算密度大于1.0g/cm3的单质炸药时，本公式相对误差不大于3 。 3、本程序不适用于含氯、氟的炸药. -KJ formula dialog box to write a VC program to
