| Abstract: | With consideration of frequency function of signal processing circuit, a generalized range equation of IR system is again derived under detector noise limit and the conventional generalized range equation is modified. In this paper we also discusse the relationships between signal processor and modulator of the system with matched-filter and give a correspondent range equation, which provide a theoretical guideline for designing and evaluating the performance of IR system. |
