Parameter Estimation of LFM Signal in Low Signal-to-Noise Ratio Using Cross-Correlation Function
The pulse with intra-pulse modulation plays an important role in the design of radar systems. The first class of the signals type is the linear frequency modulation technique.

Direction finding of correlated sources in extremely low SNR environment [PDF]
Direction-Finding (DF) in low Signal-to-Noise Ratio (SNR)environments presents challenges in accurate Angle-of-Arrival (AOA)estimation, resolution, and maximum detection range due to extrinsicsources and hardware imperfections, particularly when dealing ...

Prospects of FMCW-based frequency diverse array radar
The linear frequency modulated (LFM) frequency modulated continuous wave (FMCW)-based frequency diverse array (FDA) radar concept is investigated in detail. The radar operates as a linear pulsed FMCW/FDA in the transmission (TX) mode while it operates as

A prototype rule based system for electronic warfare [PDF]
This thesis examines the feasibility of using an expert system to solve the threat identification problem in the radar signal environment. Such systems can be used to support the Electronic Warfare Officer (EWO) in decision- making.

The Power Gain Difference Method Analysis
In this paper, we propose a new approach to passively locate the 3D position of a signal source. This novel technique, called the power gain difference (PGD), is based only on measuring the received signal strength (RSS) with multiple sensors deployed in
