IRST system: hardware implementation issues

摘要

Abstract: Generally, Infrared Search and Track systems use linear focal-plane-arrays with time-delay and integration, because of their high sensitivity. However, the readout is a cumbersome process and needs special effort. This paper describes signal processing and hardware (HW) implementation issues related to front-end electronics, non-uniformity compensation, signal formatting, target detection, tracking and display system. This paper proposes parallel pipeline architecture with dedicated HW for computationally intensive algorithms and SW intensive DSP HW for reconfigurable architecture.!9
