Effective non-cooperative target recognition NCTR systems reduce the time to engagement and also the incidence of fratricide. When combining sensors, however, even a quite coarse sensor of one type can cause a huge increase in the value of another, more fine-grained sensor.
Moreover, the availability of the fusion products allows each sensor to leverage information from other sensors to improve its performance. One is a refinement of CCD. This may not work in terrain that may mask the challenge, response, or response sharing.
The traditional dimensionality reduction algorithms for HRRP recognition are based on a reconstruction model like principal component analysis PCA [ 3 ]. Source 1b is a source, perhaps manmade, that illuminates the target, such as a searchlight or ground radar transmitter.
Quill launched inwas the first radar satellite, essentially a prototype. Vulnerability to jamming will generally increase withgrowing radar sensitivity and the evolving Digital Radio Frequency Memory DRFM based deceptive jammer technology and its broad proliferation. This is part of the general upgrading of the P-3 to make it a capable land surveillance platform.
Temporal resolution describes the intervals at which the target is sensed. The basisc of JEM is described in.
Strip map imaging observes terrain parallel to the flight path or along a specified ground path. Retrieved 19 August Spectral resolution is the number of discrete frequency or equivalent bands recorded in an individual pixel.
Federation of American Scientists.
Most scanning sensors have an array of detectors such that the IFOV is the angle subtended by each detector and the AFOV is the total angle subtended by the array. In the Center for MASINT Studies and Research list, mechanical vibrations, of different sorts, can be measured by geophysical acoustic, electro-optical laser, or radar sensors.
In an era of budget demands, however, this extremely costly new generation has not been launched. The NCTR module will consist of a classifier that uses a representation of the target density function at a number of different aspect angles coupled with a fusion module that can fuse multiple measurements collected over time.
One is a refinement of CCD. Then, dimensionality is reduced to extract the main features of the range profiles and to reduce the unwanted information; additionally, this approach lightens the computational burden since there is no need to reconstruct the initial profile.
An example of coupling might be that Sensor 3 will only look for backscatter radiation after the speed-of-light delay from Source 3a to the target and back to the position of Sensor 3b.
This research and development effort could lead to clear understanding of fundamental repeater jammer limitations - particularly of the DRFM variety - and of techniques to counter such threats both in existing radar systems,through upgrades, and in future radars.

This proposal is concerned. The true three-dimensional size and shape of a target - an important metric for automatic target recognition - can thus be estimated. Cross-range resolution in the 2D ISAR images is.
Driving research into Non-Cooperative Target Recognition (NCTR) is the fratricide problem, which, according to Army Maj. Bill McKean, is that " our weapons can kill at a greater range than we can identify a target as friend or foe.
Another group evaluated the PCR technology in an environment like that of a naval task group Ships have.
