A Study of Ineffective Investment Trust and Precious Metal Mining Issues [PDF]
, 1937 Inobject/target reconstruction and recognition based on laser radar data, the range value's accuracy is important. The range data accuracy depends on the accuracy in the laser radar's detector, especially the algorithm used for time-of-flight estimation.

Statistical analysis of the radar cross section of two small fixed‐wing drones using typical flights
IET Radar, Sonar & NavigationThe presence and importance of small drones (unmanned aerial vehicles) are increasing. With traditional radar detection the target radar cross section and its statistical properties are needed in order to design the detector and to assess detection ...

A radar-echo model for Mars [PDF]
Researchers developed a radar-echo model for Mars based on 12.6 cm continuous wave radio transmissions backscattered from the planet. The model broadly matches the variations in depolarized and polarized total radar cross sections with longitude observed

Radar cross section (RCS) measurements [Testing ourselves]
IEEE Antennas and Propagation Magazine, 2013 The radar cross section (RCS) is a critical parameter that describes the electromagnetic wave – target interaction. Its accurate prediction has long been a hot research and engineering topic. Today, RCS prediction of real targets is achieved via either numerical simulations or measurements. Here, indoor RCS measurements are reviewed in a tutorial.
