High Duty Cycle to Low Duty Cycle: Echolocation Behaviour of the Hipposiderid Bat Coelops frithii
Laryngeally echolocating bats avoid self-deafening (forward masking) by separating pulse and echo either in time using low duty cycle (LDC) echolocation, or in frequency using high duty cycle (HDC) echolocation. HDC echolocators are specialized to detect fluttering targets in cluttered environments. HDC echolocation is found only in the families Rhinolophidae and Hipposideridae in the Old World...
متن کاملDiscrete Frequency and Phase Coding Waveform for MIMO Radar
In multi-input multi-output (MIMO) radar system, good orthogonality between transmitting waveforms will fairly simplify the signal processing, along with improve the targets detection as well as the parameters estimation performance of the system. In this paper, a discrete frequency and phase coding waveform (DFPCW), which attains good orthogonality by varying the carrier frequency and initial ...
متن کاملNALM-based, phase-preserving 2R regenerator of high-duty-cycle pulses.
We explore the potential of the nonlinear amplifying loop mirror (NALM)-based phase-preserving 2R (reamplification and reshaping) regenerator for simultaneous regeneration of multiple wavelength-division-multiplexed (WDM) channels. While not considering nonlinear multi-channel propagation, we address two issues of the phase-preserving NALM that appear to us as the major obstacles in adopting it...
متن کاملHigh duty cycle and continuous terahertz emission from germanium
In the far-infrared wavelength or terahertz frequency range ~1–10 THz! there are a wide variety of potential applications for compact and tunable lasers. High resolution spectroscopy is relevant to such diverse fields as astronomy, biochemistry, and physical chemistry. Objects of interest include star-forming regions in the universe, heavy ligands in biomolecules which vibrate and rotate with a...
متن کاملEvolution of high duty cycle echolocation in bats.
Duty cycle describes the relative 'on time' of a periodic signal. In bats, we argue that high duty cycle (HDC) echolocation was selected for and evolved from low duty cycle (LDC) echolocation because increasing call duty cycle enhanced the ability of echolocating bats to detect, lock onto and track fluttering insects. Most echolocators (most bats and all birds and odontocete cetaceans) use LDC ...
