Performance Tradeoffs of Joint Radar-Communication Networks
, 2018 This letter considers a network where nodes share a wireless channel to work in turn as pulse radars for target detection and as transmitters for data exchange. Radar detection range and network throughput are studied using stochastic geometry tools.

Science, 1966 The tropopause has been detected by ultrasensitive, narrow-beam, microwave (10.7-centimeter) and ultrahigh-frequency (71.5-cm) radars. Its reflectivity is consistent with that expected theoretically for a refractively turbulent medium. Indications are that the layer is also mechanically turbulent, and that electromagnetic scatter techniques may be used

Periscope detection radar [PDF]
Proceedings International Radar Conference, 2002 The periscope detection problem is described. An advanced simulation model is developed which allows the performance of advanced periscope detection radars to be determined. An advanced system employing three-dimensional filters and distribution-free CFAR is postulated.

Broadband Low-RCS Linearly Polarized Metasurface–Based Antenna
International Journal of Antennas and PropagationIn this paper, a broadband linearly polarized (LP) metasurface (MS)–based antenna with low radar cross section (RCS) over a wideband is proposed. The radiation and scattering mechanisms of the antenna are analyzed under the guidance of characteristic ...
