Analog Modules (AMI) has introduced its next-generation Model 744DP Laser Spot Tracker Module, building on 55 years of laser spot tracker (LST) design experience to provide a compact, configurable solution for missile and platform tracker applications.
Scheduled for availability in Q1 2027, the Model 744DP provides azimuth and elevation data for tracked targets and supports NATO STANAG 3733 and pulse repetition frequency (PRF) codes. Optimized for a wavelength of 1.06 µm, the module combines high sensitivity, a wide linear dynamic range and adaptive noise tracking thresholds.
The module features a temperature-controlled silicon PIN detector, available in two standard active-area sizes of 5.33 mm or 14.1 mm. Five independent noise detection channels establish tracking thresholds for varying background light conditions and spot positions, while dedicated circuitry provides resistance to sunlight blinding across individual or multiple detector quadrants.
The detector and integrated front-end electronics are enclosed in a hermetically sealed can, mounted to a compact two-board stack containing analog and digital processing circuits. Individual channels are digitized using a high-speed analog-to-digital converter, with tracking information delivered through a serial digital interface. Azimuth and elevation outputs are normalized independently of signal strength.
Adaptive threshold control supports signal-to-noise performance, while user commands enable adjustment of gain, thresholds, tracking logic, acquisition rules, PRF codes and pulse interval modulation (PIM) sequences.
Designed with size, weight, power and cost (SWaP-C) considerations in mind, the Model 744DP measures 1.96 inches in diameter by 1.21 inches and offers a wide field of view. Additional capabilities include rangefinding support using an external T0 signal.
Multiple configurations will be available, including an optional mechanical housing incorporating optics and a narrowband interference filter to provide a complete plug-and-play semi-active laser (SAL) seeker module.
Analog Modules is currently working with customers to review platform requirements and custom configurations prior to availability in early 2027.
