UNCLASSIFIED UNCLASSIFIED

  • Legacy Missile Warning Sensors

(MWS) typically required only stimulation, not simulation

  • Legacy stimulators typically provide a

signal to “ring the bell,” not necessarily accurately simulate the threat

UNCLASSIFIED UNCLASSIFIED

  • Modern MWS systems are more

sophisticated and require threat- representative simulations for testing

  • Legacy stimulators typically cannot

provide this level of fidelity

  • Simulators, not stimulators, are

needed to produce threat- representative signals

SLIDE 24

UNCLASSIFIED UNCLASSIFIED

  • JMITS, TAPS, and MSALTS are unified by a

common methodology

  • Based on “SMEOS Programming Formulation”,

the original programming methodology

  • Allows for commonality and comparison between

test events

  • Methodology uses approved models and takes

spectral responses and atmospherics into account

Missile Simulator Programming Methodology

24

slide-25
SLIDE 25

UNCLASSIFIED UNCLASSIFIED

  • Define missile simulation parameters

–Missile type –Engagement geometry –One-to-one simulation or not

  • Generate fly-out model using Threat

Modeling and Analysis Program (TMAP)

Methodology (continued)

25

slide-26
SLIDE 26

UNCLASSIFIED UNCLASSIFIED

  • Use Enhanced Missile Signature (E-

MSIG) database to extract missile signature as a Source Radiant Intensity (SRI) in the SUT spectral response –Must know SUT spectral response

Methodology (continued)

26

slide-27
SLIDE 27

UNCLASSIFIED UNCLASSIFIED

  • Propagate the SRI signature through

the simulated atmospheric conditions from the missile to the SUT –MODTRAN for IR, OSIC for UV

  • Result is irradiance on the SUT

aperture in the SUT spectral band

  • This result is what the simulator must

produce

Methodology (continued)

27

slide-28
SLIDE 28

UNCLASSIFIED UNCLASSIFIED

  • The simulator spectral band will most

likely not be the same as the SUT band

  • Requires bandpass conversion from

simulator to SUT

  • At time of simulation, account for

current atmosphere

Methodology (continued)

28

slide-29
SLIDE 29

UNCLASSIFIED UNCLASSIFIED

  • During testing, small variations in the

atmosphere and emitters occur which must be accounted for

  • A normalization measures these

variations to account for them

  • Performed regularly throughout the

test
