Towards Dual-functional Radar-Communication Systems: Optimal Waveform Design [PDF]

, 2017
We focus on a dual-functional multi-input-multi-output (MIMO) radar-communication (RadCom) system, where a single transmitter communicates with downlink cellular users and detects radar targets simultaneously.

Scattering statistics of rock outcrops: Model-data comparisons and Bayesian inference using mixture distributions [PDF]

, 2019
The probability density function of the acoustic field amplitude scattered by the seafloor was measured in a rocky environment off the coast of Norway using a synthetic aperture sonar system, and is reported here in terms of the probability of false ...

Special aspects of modulation RCS measurement in Ka-band [PDF]

ITM Web of Conferences, 2019
Radar reflectors are used as standards for radioelectronic devices calibration, as navigation beacons for air and naval traffic control and for radar visibility increase. Controlled (parametric) reflectors change reflected signal characteristics.

Subinteger Range-Bin Alignment Method for ISAR Imaging of Noncooperative Targets

EURASIP Journal on Advances in Signal Processing, 2010
Inverse Synthetic Aperture Radar (ISAR) is a coherent radar technique capable of generating images of noncooperative targets. ISAR may have better performance in adverse meteorological conditions than traditional imaging sensors.

Vital-Signs Detector Based on Frequency-Shift Keying Radar

Sensors, 2020
A frequency-shift keying (FSK) radar in the 2.45-GHz band is proposed for highly accurate vital-signs detection. The measurement accuracy of the proposed detector for the heartbeat is increased by using the cross-correlation between the phase differences

Feature Extraction for Moving Targets Based on the Statistical Characteristics of Echo Amplitude with the L-Band Fully Polarimetric Radar

Remote Sensing, 2022
Non-imaging radar can achieve the detection and localization of moving targets, but it faces difficulties in the classification of targets. Aiming for the application of moving target classification by low/medium resolution non-imaging radar, this paper ...
