Developments in target micro-Doppler signatures analysis : radar imaging, ultrasound and through-the-wall radar [PDF]
, 2013 Target motions, other than the main bulk translation of the target, induce Doppler modulations around the main Doppler shift that form what is commonly called a target micro-Doppler signature.

Object identification and tracking by quantum radar
Quantum Technologies and Quantum Information Science V, 2019 Quantum Radar is a promising technology that could have a strong impact on the civilian and military realms. In this study we introduce a new concept design for implementing a Quantum Radar, based on the time and polarization correlations of the entangled photons for detection and identification and tracking of high-speed targets. The design is focused

Radar matched filtering using the fractional fourier transform [PDF]
, 2010 -A matched filter is the optimal linear filter for maximizing the signal to noise ratio (SNR) in the presence of additive noise. Matched filters are commonly used in radar systems where the transmitted signal is known and may be used as a replica to be ...

Bee World, 1999 The flight patterns of bees have been studied for over 100 years, but due to their small size, bees can only be tracked by eye for a very short distance from the nest or hive. Scientists have employed various techniques, including mark-recapture, feeder experiments, homing experiments and the interpretation of bee dances, to investigate bee foraging ...
