Many missile–target simulation systems use random numbers to mimic the effects of a fluctuating target Radar Cross Section (RCS) in an attempt to minimise simulation times. In this paper a Genetic Algorithm is used to optimise the complexity of a pointscatterer model with a realistic radar cross section, ultimately allowing real measured data to be used in simulations. The performance of the ge...

The radar cross section of spherical retroreflectors operating at terahertz frequencies is investigated. Several spherical retroreflectors with diameters ranging from 2 mm to 8 mm were fabricated and their radar cross section was measured at 100 GHz, 160 GHz, and 350 GHz. A frequency selective surface was applied to the retroreflectors to demonstrate proof of concept of narrow-band terahertz re...

A scheme for multitarget identification and localization using bistatic MIMO radar systems is proposed. Multitarget can be distinguished by Capon method, as well as the targets angles with respect to transmitter and receiver can be synthesized using the received signals. Thus, the locations of the multiple targets are obtained and spatial synchronization problem in traditional bistatic radars i...

Uncertainties in certain features of target geometries result in a loss of confidence in the signature assessment of the target. Knowledge of the impact to a target’s radar cross section (RCS) due to changes to specific target features can assist to identify whether uncertainty in a certain target feature warrants a loss of confidence in the target signature. This study will allow a development...

Lidar and radar observations from CALIPSO and CloudSat missions have allowed the development of methods to determine atmospheric parameters [1, 2]. Total aerosol optical depth (AOD) and cloud liquid water path have thus been derived at the scale of the lidar or radar footprint using AMSR-E wind speed information [3, 4], or the combination of lidar and radar observations using ocean surface echo...

An approximate method to compute rough estimates of the broadside radar return from axially symmetric ionized gas columns is presented and applied to an illustrative example The method uses a continuum approach and takes into account the electron-neuti al collision frequency and both axial and radial variation of electron density The local reflectivity is determined as a function of axial posit...
