Low Probability of Intercept/Detect (LPI/LPD) Secure Communications Using Antenna Arrays Employing Rapid Sidelobe Time Modulation

IEEE Transactions on Antennas and Propagation
We present an electronically-reconfigurable antenna array offering low probability of intercept/detect (LPI/LPD) and secure communications capabilities simultaneously at the physical layer. This antenna array is designed to provide rapidly time-varying sidelobes and a stationary main lobe. By performing rapid sidelobe time modulation (SLTM), the signal

Two Decades of Human-Elephant Conflict in Jharkhand: Spatial and Ecological Drivers of Human Fatalities. [PDF]

Ecol Evol
Conflict hotspot (human fatalities and injuries) from 2000 to 2023 in Jharkhand. ABSTRACT Human–Elephant Conflict (HEC) is a major issue in South Asia, especially in India, where rapid development and increased human–elephant overlap intensify the problem. We analyzed human fatality and injury patterns over 23 years (2000–2023) in Jharkhand, identified
