Track/Jam Record

Size: 64
Description: The following information shall be provided for each track/jam target:

* Track/Jam Field - This field shall identify the targets in an emitter track or emitters a system is attempting to jam. For single track emitter systems this field shall be used to identify the target the system is tracking. If the system is tracking a target cluster then all the targets in the cluster shall be identified in this field. The system shall not indicate a target(s) in this field if the system determines that the track has been physically offset from target(s) by jamming. This field shall be represented by an Entity Identifier Record (see 5.3.14), an Emitter Identifier and a Beam Identifier. The Emitter and Beam Identifiers shall be specified by 8-bit unsigned integers. For a tracking emission, The Emitter and Beam ID fields shall each contain zero. For a jamming emission, these identifiers are defined as follows:

* Emitter Identifier - The Emitter Identifier shall be the Emitter ID number of the emitter for which the jamming emission is intended.

* Beam Identifier - The Beam Identifier shall be Beam ID number of the emitter beam for which the jamming emission is intended.

The maximum number of emitter systems (N(max)), beams in system i (M(i-max)), and targets in track/jam beam j (P(j-max)) is a function of the maximum PDU size specified in the Standard for Distributed Interactive Simulation - Communication Services and Profiles, and must adhere to the following relationship

Record Components:

Item Name Bit Length Opt Opt Ctl Rpt Rpt Ctl
Site Identifier Field 16
Application Identifier Field 16
Entity Identity Field 16
Emitter ID Number Field 8
Beam ID Number Field 8
