Abstract:

The detection sensitivity of a guided wave radar designed to detect intruders crossing a perimeter up to two miles long is analyzed. Expressions are developed for the signal-to-noise ratio as a function of operating frequency and system properties. It is shown that performance is degraded as the operating frequency increases. The principal reason for this is the rapid rise in the attenuation of parallel leaky coaxial cables used as guided wave structures. The results indicate that satisfactory performance of such systems could be expected at frequencies up to 100 or 200 MHz. However, improved sensitivity is obtained at lower frequencies. Author
