Das Doppler-Radar als Regenmeßgerät
Durch Konvertierung des vollständigen Spektrums der Dopplergeschwindigkeit in entsprechende Tropfenverteilungen (Tropfenfallgeschwindigkeit nach Gunn und Kinzer) und Integration über alle Tropfen erhält man den Flüssigwassergehalt des Regens und die ...

New ranging algorithm for FM/CW radars [PDF]
A new ranging algorithm for frequency modulated/continuous wave (FM/CW) radars is given. This algorithm is near optimal, very robust, does not depend on the type of modulation, and is fairly easy to compute. An example of an older algorithm based on sinusoidal frequency modulation (FM) used on the MK-95 CW radar is given to illustrate shortcomings in ...

Velocity Dealiased Spectral Estimators of Range Migrating Targets using a Single Low-PRF Wideband Waveform [PDF]
Wideband radars are promising systems that may provide numerous advantages, like simultaneous detection of slow and fast moving targets, high range-velocity resolution classification, and electronic countermeasures.

Highly Versatile Real‐Time Optical Noise Filtering Through Temporal Cloaking
Conventional bandpass filtering strategies may be insufficient for recovering optical waveforms under extremely noisy conditions. We demonstrate a temporal‐cloaking denoising strategy enabled by the temporal Talbot effect, which concentrates the coherent signal of interest into short temporal slots while broadband noise remains temporally spread.

Inter-radar interference analysis of FMCW radars with different chirp rates
Millimetre-wave frequency-modulated continuous wave (FMCW) radar is expected to be widely deployed for advanced driver assistance systems (ADAS) and self-driving cars. Considering that automotive radars will be deployed in a huge number of cars in future,

A Decade of Airborne Electromagnetic Surveying Lake Menindee (Australia) Under Varying Water Levels
ABSTRACT Time domain airborne electromagnetic (AEM) surveying is a mature geophysical tool for imaging the Earth's shallow subsurface. It produces images of the electromagnetic conductivity structure of the earth, down to depths of a few hundred metres.
