- The Two-axis Rate Table
- Wide Band Collimator
- Seeker Control and Data Capture System
Two-axis Rate Table
The two-axis rate table was developed to determine the maximum angular rate at which the tracking section of a IR guided missile can track a target.
The system can be used to measure the angular rate of rolling and non-rolling airframe IR missile seekers. When testing non-rolling airframe missiles, only one axis is used. As rolling airframe seekers normally only have one set of steering canards, the rolling of the airframe allows the missile to steer in 3 dimensions. To ensure that the measurement results are representative of the actual performance for the missile, the seeker is rolled during the angular rate measurement.
Wide Band Collimator
The wide band collimator is used as a simple scene projector (using point sources) during the evaluation of IR guided missile seekers. Improved counter counter measure techniques used in newer IR missile seekers, employ a variety of techniques to counter the effects of decoys. The spectral band of the wide band collimator is 0.5um to 12 um and this is what makes it unique. It has a view angle of +/- 5 degrees and allows one target and 4 decoys to be simulated with different IR spectra. The trajectories of the 4 decoys can be independently controlled. These features enable a range of counter countermeasure techniques to be simulated and the effects of decoys to be evaluated.
