In the global game of nuclear brinksmanship, secrets are the coin of the realm. This was especially true during the Cold War, ...

The magnetic loop antenna is a familiar sight in radio amateur circles as a means to pack a high performance HF antenna into ...

Abstract: Over-the-horizon radar (OTHR) utilizes the ionospheric refraction and reflection in high-frequency (HF) band for air-sea targets detection. However, nonstationary ionospheric dynamics induce ...

Abstract: In this letter, we introduce an adaptive multiple path loss exponent (AMPLE) radio propagation model considering environmental factors. The AMPLE model aims at predicting path loss with low ...
