Time delay estimation has been a research topic of significant practical importance in many fields (radar, sonar, seismology, geophysics, ultrasonics, hands-free communications, etc.). It is a first stage that feeds into subsequent processing blocks for identifying, localizing, and tracking radiating sources. This area has made remarkable advances in the past few decades, and is continuing to p...

Burial grounds are commonly surveyed and searched by both police/humanitarian search teams and archaeologists. One aspect of an efficient search is to establish areas free of recent internments to allow the concentration of assets in suspect terrain. While 100% surety in locating remains can never be achieved, the deployment of a red, amber green (RAG) system for assessment has proven invaluabl...

high resolution range profile (hrrp) is being known as one of the most powerful tools for radar target recognition. the main problem with range profile for radar target recognition is its sensitivity to aspect angle. to overcome this problem, consecutive samples of hrrp (or feature vectors extracted from them)were assumed to be identically independently distributed (iid) in small frames of aspe...
