“…The DNL values lie between AE0:6 least significant bit (LSB), which verifies the 10-bit accuracy and monotonicity. The integral nonlinearity of the emitter current is of no significance and thus not presented here, because the exponential nature of the Planck function inherently yields a highly nonlinear relationship between IR radiance and emitter current [11].…”

This letter presents a mismatch-tolerant read-in integrated circuit (RIIC) with voltage-drop compensation applicable to high-speed and hightemperature infrared scene projectors. A current-programmed unit pixel is designed to compensate for ground-line voltage drops, thus improving the array-wide current uniformity. The proposed mismatch-tolerant design circumvents non-monotonic fluctuations in the output current, irrespective of the matching properties of sampling capacitors and switches. A prototype RIIC with a 32 × 32 unit-pixel array is fabricated in a 0.18-µm CMOS process. The RIIC compensates for voltage drops up to 500 mV with error currents below 1 µA and achieves 10-bit accuracy with output-current nonmonotonicity eliminated.

“…[1][2][3][4][5][6] It is designed to provide closed-loop dynamic simulations of complex scenarios that include moving objects, composite backgrounds, sources of radiation and precise radiometry. The main simulation scenarios may be classified into the following three groups: (1) air scenario with aircrafts and backgrounds, (2) maritime scenario with boats, ships and ocean waves, and (3) land scenario with land objects in composite terrain environments.…”

[1][2][3][4][5][6] Initially, VIRSuite was developed for generating imagery for aircraft scenarios in the MWIR band only. It was later extended to generate MWIR, LWIR, visual scenery and range imagery for LADAR scene generation.…”

This paper describes development of two key functionalities within the VIRSuite scene simulation program, broadening its scene generation capabilities and increasing accuracy of thermal signatures. Firstly, a new LADAR scene generation module has been designed. It is capable of simulating range imagery for Geiger mode LADAR, in addition to the already existing functionality for linear mode systems. Furthermore, a new 3D heat diffusion solver has been developed within the VIRSuite signature prediction module. It is capable of calculating the temperature distribution in complex three-dimensional objects for enhanced dynamic prediction of thermal signatures. With these enhancements, VIRSuite is now a robust tool for conducting dynamic simulation for missiles with multi-mode seekers.

“…Right now, there is a wide variety of real-time emulators, most of them are commercialize by important companies such as National Instruments, dSPACE, OPAL-RT, RTDS, as well as noncommercial options developed by different universities [1,19]. Different embedded technologies are used taking advantage of their architecture settings to maximize the design such as DSPs [20,24,[29][30][31], graphics processing unit [7,14,[16][17][18]25], FPGAs [2,5,6,15,23,27], and genericuse processors. The opportunities to apply these realtime simulators in engineering are wide and vary due to the several advantages [11] that bring such as cost, prototypes speed, fidelity, and results consistency.…”

In this paper, we present a teaching methodology based on a low‐cost embedded system platform that is easy to use and replicate, oriented to real‐time simulation project development. Designed for real‐time implementation of coding generated with MPLAB Device Blocks for Simulink. The purpose of this methodology is that students, teachers, and professionals will be able to carry out a theoretical project of a simulation in a computer, which includes complex mathematical modeling, to interact with its environment in real‐time. This system has been utilized already by students of Engineering of the first semesters as well as professors and researchers in updated and initialization courses in embedded systems within the University of Guadalajara. Finally, in the results section, we show a comparison of the proposed platform and a dSPACE platform applied in a control problem with an intricate mathematical model to process through a Hardware‐in‐the‐loop (HIL).
