Signal processing and radio ranging system. |
摘要 |
<p>A radio slant ranging system having a bank of range gates producing outputs X, 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 All of the transform:-and then forming the arctangent of A1I/-A1R. The signal processing method used in the system may have more general application.</p> |
