Class - SecondarySurveillanceRadar
<< feature >> Logical View.AIXM.AIXM Features.Surveillance
<<feature>> Secondary Surveillance Radar (SSR aka Secondary Radar (SECRA)) is a radar system in which the object to be detected is fitted with the cooperative equipment in the form of a radio receiver/transmitter (transponder). Radar pulses transmitted from the searching transmitter/receiver (interrogator) site are received in the cooperative equipment and used to trigger a distinctive transmission from the transponder. This reply transmission, rather than a reflected signal, is then received back at the transmitter/receiver site for processing and display at an air traffic control facility.
Inheritance
This is a specialization of the SurveillanceRadar class and it inherits all attributes and associations of that class.
List of attributes
| Name | Data Type | Definition | ||
|---|---|---|---|---|
| transponder | CodeTransponderType | Mode S, or mode select, despite also being called a transponder radar system replacement for Air Traffic Control Radar Beacon System (ATCRBS), is actually a data packet protocol which can be used to augment ATCRBS transponder positioning equipment (radar and TCAS). Mode S is designed to fully interface with ATCRBS systems: mode S SSRs can interrogate ATCRBS transponders, and AIS-P transponders will also reply to older ATCRBS and TCAS interrogations. | ||
| autonomous | CodeYesNoType | Indicates the SRR is autonomous or independent. | ||
| monopulse | CodeYesNoType | Monopulse radar is an adaptation of conical scanning radar which sends additional information in the radar signal in order to avoid problems caused by rapid changes in signal strength. The system also makes jamming more difficult. Most radars designed since the 1960s are monopulse systems. | ||
| verticalCoverageAltitude | ValDistanceVerticalType | Altitude for which the Radar provides vertical coverage. | Inherited from SurveillanceRadar | |
| verticalCoverageDistance | ValDistanceType | Distance for which the Radar provides vertical coverage. | Inherited from SurveillanceRadar | |
| verticalCoverageAzimuth | ValBearingType | Azimuth for which the Radar provides vertical coverage. | Inherited from SurveillanceRadar | |
| antennaTiltFixed | CodeYesNoType | Indicates whether the antenna tilt is Variable or Fixed. | Inherited from SurveillanceRadar | |
| tiltAngle | ValAngleType | Angle at which the antenna is tilted. | Inherited from SurveillanceRadar | |
| automatedRadarTerminalSystem | TextDesignatorType | The Automated Radar Terminal System (ARTS) is a system in the air traffic control system using radar intelligence to detect and display pertinent data such as flight identification, altitude, and position of aircraft operating in the terminal area. A Radar with this attribute automatically tracks controlled aircraft and presents alpha-numeric information adjacent to their targets. It may even automatically calculate the separation between different aircrafts and provide an alert if that separation is compromised as per the set standards. | Inherited from SurveillanceRadar | |
| name | TextNameType | Textual name of the equipment. | Inherited from RadarEquipment | |
| serialNumber | TextDesignatorType | Serial number of the equipment. | Inherited from RadarEquipment | |
| range | ValDistanceType | The applicable range of the equipment to detect aircraft. | Inherited from RadarEquipment | |
| rangeAccuracy | ValDistanceType | Accuracy of the applicable range of the equipment to detect aircraft. | Inherited from RadarEquipment | |
| dualChannel | CodeYesNoType | Indicates whether the component has dual frequency. | Inherited from RadarEquipment | |
| movingTargetIndicator | CodeYesNoType | Indicates whether a Moving Target Indicator (MTI) is available for the component. The MTI function eliminates ground clutter. | Inherited from RadarEquipment | |
| standbyPower | CodeStandbyPowerType | Indicates how the component is powered if the primary power fails. | Inherited from RadarEquipment | |
| digital | CodeYesNoType | Indicates if the radar equipment is digital or analogue. | Inherited from RadarEquipment | |
| militaryUseOnly | CodeYesNoType | Indicates the equipment is for military use only. | Inherited from RadarEquipment | |
| specialUseOnly | CodeYesNoType | Indicates the equipment is for special use procedures only such as Helipads, etc. | Inherited from RadarEquipment | |
| specialAircraftOnly | CodeYesNoType | Indicates the equipment is to be only used for certain type of aircraft that are capable of using it. In some instances, the slope angle or procedure can only be flown by high performance aircraft. | Inherited from RadarEquipment | |
| magneticVariation | ValMagneticVariationType | The angular difference between True North and Magnetic North measured at a given position and date. | Inherited from RadarEquipment | |
| magneticVariationAccuracy | ValAngleType | Accuracy of the magnetic variation. | Inherited from RadarEquipment | |
| dateMagneticVariation | DateYearType | The date on which the magnetic variation had this value. | Inherited from RadarEquipment |
