Description
Summary:This paper will report the results of the study of the sensitivity of digital EW receivers. The best sensitivity one can expect from an EW receiver is achieved by designing the bandwidth of the receiver to match the pulse width of the input signals. Under this condition, the receiver can be considered as a matched filter. However, it is probably difficult to design an EW receiver which will perform as a matched filter to every input signal, although theoretically this can be done. This paper will provide an approach to improve the sensitivity of the receiver with reasonable complexity. Presented at the IEEE 1990 National Aerospace and Electronics Conference (NAECON 1990) held in Dayton, Ohio, on 21-25 May 1990.
