TARGET DETECTION AND TRANSMITTAL
Radar Surveillance is provided by Advanced Radar Surveillance System (ARSS), Perimeter Surveillance Radar System (PSRS), or Manportable Surveillance and Target Acquisition Radar (MSTAR). Each radar unit reports data to its associated controller station.

When a target is detected by one of the radar units, target information is received at the radar unit's associated controller station. XML Messages are transmitted to the ASN computers. The program XML_Comm translates and processes the data into alarm data displayed in ASN's Alarm Resolution and in the graphics display.

ANNUNCIATION
Target detection is displayed in both Alarm Resolution and in the graphics program.
Alarm Resolution

	The sensor controller reports target detection and an alarm is generated in Alarm Resolution. There is only one alarm line per radar device. An additional target detected will cause the same alarm line to annunciate again.
	A target detection on a different radar device will generate a new alarm line in Alarm Resolution.
	When an alarm line is acknowledged, it will stop flashing in Alarm Resolution.

GRAPHICS
Target movement is also tracked in the graphics program for as many as 25 iterations of the target. On receipt of the 26th track, the oldest track is erased.

When an alarm is acknowledged, the icon will stop flashing, but tracking will continue in the graphics program. When an alarm line is reset, the target track will be erased. If the target is still active, the radar will continue to send information and the target will be reported as if it were a new detection.

Target Representation can be configured to set the colors and sizes of the target circles to be graphically displayed for each target classification as reported by the radar.

PRODUCT FEATURES

	Certified ASN characteristics are maintained.
	Provides a single interface platform for operators.
	Alarm information remains in a standard, easy-to interpret format in Alarm Resolution.
	Uses standard XML Interface protocol.
	Each radar sensor will be assigned its own panel number for simplified identification.
	Zone, or mode, configuration allows for masking areas for the radar. PSRS radars have "exclusion zones" for which detections in the mask area are ignored. ARSS and MSTAR radars detect within a defined minimum and maximum range, azimuth, and elevation.
	Zone configuration provides the capability to change the surveillance areas(s) of radars for different needs (e.g., Day / Night). Once the modes have been defined and configured, the ASN operator can easily select surveillance mode from iGraphics.
	Target representation configuration is used to set the colors and sizes of target circles for easy identification.

SPECIFICATIONS
Supported radar devices include:

	PSRS (Perimeter Surveillance Radar System)
	ARSS (Advanced Radar Surveillance System)
	MSTAR (Manportable Surveillance and Target Acquisition Radar)
	A maximum of twenty (20) Radar Units (mixture of long and short range) can be supported.
	The system can support a maximum of 100 simultaneous target tracks (system wide). This is measured by 100 / # of radar units in the configuration. For example, if there are 10 radar units in the configuration, each radar unit can support up to 10 simultaneous target tracks.
	The graphics program can display a maximum of 25 target steps per track.
	Target movement is reported as frequently as it is received from the radar
	In the event of adjacent radars having overlapping surveillance areas, a single target may be detected by multiple radars at the same time. When this happens, all radars will report the event on separate lines in Alarm Resolution
