Abstract :
The effect of fading due to multipath is seldom accounted for in the assessment of the vulnerability of frequency hopped communications systems to radiometric intercept threats. However, the results derived in the paper illustrate that fading due to multipath could significantly improve the ability of a radiometer to detect frequency hopped signals transmitted at sea
