Paper Abstract
The emergence of spectrally multimode smart missiles requires hardware-in-the-loop (HWIL) facilities to simulate
multiple spectral signatures simultaneously. While traditional diode-pumped solid-state (DPSS) sources provide a great
basic testing source for smart missiles, they typically are bulky and provide substantially more power peak power than
what is required for laboratory simulation, have fixed pulse widths, and require some external means to attenuate the
output power. HWIL facilities require systems capable of high speed variability of the angular divergence and optical
intensity over several orders of magnitude, which is not typically provided by basic DPSS systems. In order to meet the
needs of HWIL facilities, we present a low-cost semi-active laser (SAL) simulator source using laser diode sources that
emits laser light at the critical wavelengths of 1064 nm and 1550 nm, along with light in the visible for alignment, from a
single fiber aperture. Fiber delivery of the multi-spectral output can provide several advantages depending on the testing
setup. The SAL simulator source presented is capable of providing attenuation of greater than 70 dB with a response
time of a few milliseconds and provides a means to change the angular divergence over an entire dynamic range of 0.02-
6º in less than 400 ms. Further, the SAL simulator is pulse width and pulse repetition rate agile making it capable of
producing both current and any future coding format necessary.
