Non cooperative target recognition information technology essay

It is well known that bistatic and multistatic radar are a potential means of defeating low-radar-observability aircraft. Power-level detector with cross-collation of a local copy of the pulse against the received signal. Detection of mines, both on the active battlefield and in reconstituting nations with unexploded ordnance UXO remains a critical problem.

Retrieved 18 October Where COBRA JUDY is built into a ship, this dual frequency S- and X-band radar is transportable, capable of operating on ships or on land, and optimized for monitoring medium range ballistic missiles and antimissile systems.

The antenna is oriented toward the west, monitoring the northern Pacific missile test areas. Radiometric resolution is the number of levels of energy recorded, per pixel, in each spectral band.

Its use in measuring the ground motion of earthquakes can complement seismic sensors for detecting concealed underground explosions, or the characteristics of those above ground.

Putting sensitive and selective, or otherwise complementary sensors, into the same reconnaissance or surveillance system enhances the capabilities of the entire system, as in the Rocket Launch Spotter.


TDOA works with a set of reflections, from the same target, arriving at multiple points. Archived from the original on 7 July These techniques, which could work if IFF systems fail, have been especially secret.

This simulation is called the synthetic aperture. We then describe several potential techniques to counter repeater jammers, whose respective enabling technologies are deemed to exist. Depending on the type of radiation and sensor in use, the atmosphere can have little interfering effect, or have a tremendous effect requiring extensive engineering to overcome.

It is also a requirement, from operations personnel concerned with shallow water [21] operations. Friendly forces identify in response, and the interrogators share the data. Thus, non cooperative target recognition gets less computationally intensive and has potential for real time processing.

Recognizing the threat of ground surveillance radar, [9] the Australian military is exploring personal radar warning receivers RWRapproximately the size of a credit card, and intended principally for special operations forces who have to evade ground surveillance radar.

Where COBRA JUDY is built into a ship, this dual frequency S- and X-band radar is transportable, capable of operating on ships or on land, and optimized for monitoring medium range ballistic missiles and antimissile systems.

Field ManualIntelligence. Another technique was to absorb some of the radar in the coating of the aircraft.

New Non-Cooperative Target Recognition (NCTR) Techniques Development

The fusion module will consist of a Bayesian Network that updates beliefs about what type of target is being measured by taking into consideration a priori information regarding the types of airborne objects in an area and the capabilities of the sensors providing measurements.

Measurement and Signals Intelligence". For example, the DIA list considers vibration. It comes from the fact that the intensity of a HRRP is a function of the radar transmitting power, target distance, radar antenna gain, receiver gain, system losses and so on, thus, profiles measured by different radars or under different conditions will have different amplitude scales.

Compare radar CCD and optical equivalents of the same subject. A system originally called Lacrosse or LacrosIndigo, and finally Onyx appears to be the only US radar satellite system, using pushbroom scans and "spotlighting" SAR. The amplitude modulation comes from moving surfaces of different reflectivity and angle of reflection.

Once the ground signatures are complete, runs are made over the test area. Active sensors[ edit ] Active sensors are conceptually of two types, imaging and non-imaging.

The basisc of JEM is described in. They are separated into several processing categories, and include both passive and activeapproaches.

A framing sensor, such as a conventional camera, records the received radiation as a single object. In SeptemberDARPA demonstrated real-time onboard change detection vehicles and IEDs and rapid ground-station tomographic processing, as well as rapid generation of bald earth digital elevation models DEMs using stereo processing.

Non-cooperative Target Detection/Identification (ID)

This proposal is concerned with waveform and processing techniques to enable existing radar systems to maintaintheir operational performance in the presence of deceptive jammers. Capable of validating electromagnetic models and aiding in the development of target detection algorithms, it could transmit and receive waveforms with usable bandwidth from 50 to MHz.

As noted, it is impossible to fill a database only with measured profiles since among other reasons, aircraft from hostile nations will never participate in measurement campaigns. The products of this effort are expected to be applicableto all military radars within the context of shipboard, airborne and space-borne applications.

Research on non cooperative target recognition technology based on Information Fusion Technology Hao Wang Changchun University of Science and Technology, ChangchunChina Abstract In order to study non cooperative IFF to technology, this paper detailed illustrates the D-S is a study of cooperative target.

Non-Cooperative Target Recognition by Means of Singular Value Decomposition Applied to Radar High Resolution Range Profiles †. Radar Automatic Target Recognition (ATR) and Non-Cooperative Target Recognition (NCTR) captures material presented by leading international experts at a NATO lecture series and explores both the fundamentals of classification techniques applied to data from a variety of radar modes and selected advanced techniques at the forefront of Non-cooperative Target Detection/Identification (ID) Printer-friendly version.

Award Information. Effective non-cooperative target recognition (NCTR) systems reduce the time to engagement and also the incidence of fratricide.

Sensor technology such as airborne MTI radar and ESM can also provide target recognition information at long.
