A method of processing a channel signal group. |
摘要 |
A radio slant ranging system having a bank of range gates producing outputs XI to XN which comprise ground clutter components on a thermal noise pedestal. The clutter components are regarded as defining a single sinusoidal ripple envelope on the noise pedestal and a clutter centroid tracking signal is derived by using a digital filter to calculate the real and imaginary components A1R and A1I of the transform: <IMAGE> and then forming the arctangent of A1I/-A1R. The signal processing method used in the system may have a more general application.
