This paper compares different digital receiver signal processing schemes as applied to current ESM/RWR systems. The schemes include fast fourier transform (FFT)-based, FIR filter-based and mixed architectures. Use of polyphase FFT and IIR filters is also ... see more
Vanitha D., Kundhavai R.M.
This paper presents a holistic solution to the navigation requirements in a time critical electronic warfare systems like missile warning systems (MWS). In a passive MWS using IR sensors the efficiency of the system is determined by attributes such as low... see more
P.S. Sai Pavan, B. Renuka, B. Vinatha
As the signal processing required in electronic warfare (EW) domain is complex and the sample rates to be handled are very high, IP cores which are freely available are not of much use. A study of various fast fourier transform (FFT) algorithms has been c... see more
Sunita Awasthi Singh, Bineesh P.K., Satish Shetty K.
Current and future aircraft systems require real-time embedded software with greater flexibility compared to what was previously available due to the continuous advancements in the technology leading to large and complex systems. Portability of software a... see more
