High Performance camera electronics for Infrared payloads

Abstract

In recent times, demand for Micro and Nano satellites has increased many folds, resulting in rapid development of miniaturized satellite systems. Infrared (IR) sensors find multiple applications in remote sensing. These sensors require processing electronics with high SNR. Infrared sensors require high performance electronics. This paper discusses the main challenges in design and development of miniaturized high SNR camera electronics for IR sensor system. Analog Front End (AFE) based analog video processing circuit is used in camera electronics. This paper presents design aspects, details of test results with simulated sensor as well as the integrated test results of camera electronics with sensor. Electronics PSNR (Peak Signal to Noise Ratio) $\approx$12000 is achieved. Power dissipation in Camera electronics is approximately 1.5W.
