In geometry , a monostatic polytope or unistable polyhedron is a d Convex polytope polytope which can stand on only one face . They were described in 1969 by John Horton Conway J.H. Conway , M. Goldberg and Richard K. Guy R.K. Guy . The monostatic polytope in 3 space they constructed has only 19 Face geometry faces , the record so far. Definition A polytope is called monostatic if, when filled homogeneously, is stable on only one Facet mathematics facet . Alternatively, a polytope is monostatic if its centroid the center of mass has an orthogonal projection in the interior of only one facet. Properties No convex polygon in the plane is monostatic. This was shown by Vladimir Arnold V. Arnold via reduction to the four vertex theorem . There are no monostatic simplex simplices in dimension up to 8. In dimension 3 this is due to Conway. In dimension up to 6 this is due to R.J.M. Dawson. Dimensions 7 and 8 were ruled out by R.J.M. Dawson, W. Finbow, and P. Mak. R.J.M. Dawson There exist monostatic simplices in dimension 10 and up.

Orphan date February 2009 Due to size and cost limitations, Trainer Planes are not able to accommodate a traditional radar system. Virtual Training capability consists of implementation of a virtual radar capability as well as a ground based mission management and debriefing capability. This provides an affordable solution to radar training to flight students and support future pilot training. The airborne component of the Virtual Radar provides radar capability for both Air To Air A A and Air To Ground A G radar modes without the use of radar system. The system provides data via airborne bus such as Ethernet or MIL STD 1553B, to the Mission Display Processor MDP that simulates unclassified radar data. The system may also provide RS 170 video synthesizing A G radar maps Real Beam Maps Synthetic Aperture Radar SAR maps etc . The basis of the virtual radar system is a closed loop data network. All participants in the Network can share their GPS positioning data and supplemental Air Data Computer ADC data to calculate targeting information like a radar system. All participants in the network must have a virtual radar system to either receive target data or generate target information to other participants. The Ground based portion of the Virtual Training must support training mission management when it is an active participant in the data network as well as provide post training mission debriefing capabilities with video and data review from data recorded on a Digital Video Recorder DVR . The data network must support all virtual radar requirements with or without the participation of a Virtual Training Ground system.

3D radar provides for radar coverage on three dimensions unlike the more common 2D radar . While the normal 2D radar provides range and azimuth, the 3D radar provides elevation information with range and azimuth. Applications include weather forecasting , defense and surveillance. 3D Radar Techniques Steered Beam radars steer a narrow beam through a scan pattern to build a 3 D picture. Examples include NEXRAD doppler weather radar which uses a parabolic dish and the AN SPY 1 phased array radar employed by the Aegis class of missile cruiser. br Stacked Beam radars emit and or receive multiple beams of radio waves at two or more elevation angles. By comparing the relative strengths of the returns from each beam, the elevation of the target can be deduced. An example of a stacked beam radar is the ARSR 4.

Traditional radar sends directional pulses of Electromagnetic radiation electromagnetic energy and detects the presence, position and motion of an object such as an aircraft by analyzing the portion of the energy reflected from the object back to the radar station. Imaging radar attempts to form a picture of the object as well, by mapping the electromagnetic scattering coefficient onto a two dimensional plane. Objects with a higher coeficient are assigned a higher optical reflective index, creating an optical image. Several techniques have evolved to do this. Generally they take advantage of the Doppler shift caused by the rotation or other motion of the object and by the changing view of the object brought about by the relative motion between the object and the back scatter that is perceived by radar of the object a plane flying over the earth. Through recent improvements of the techniques, this can be precisely calculated. Imaging radar has been used to map the Earth, other planets, asteroids, other celestial objects and to categorize targets for military systems.
