Synthetic Aperture Radar and Search and Rescue

2000
Scientists at the Canada Centre for Remote Sensing have explored the uses of remotely sensed imagery to assist Search and Rescue in Canada. Studies concentrated on the uses of SAR imagery for the detection and classification of crashed aircraft and have shown the feasibility of using such imagery for these purposes, although current spaceborne systems ...

Results from an experimental dual-band search radar

Radio and Electronic Engineer, 1981
The performance of surface survillence radars is complicated by temporal changes of propagation loss, sea and rain clutter and target behaviour. This paper presents short and medium-term statistics using a real time pulse-to-pulse digital analyser operated in conjunction with high dynamic range logarithmic receivers fed from an experimental dual ...

Fade Probabilities: Measures for Predicting Search-Radar Performance

IEEE Transactions on Aerospace and Electronic Systems, 1978
By itself, the cumulative probability of detection has been inadequate for accurate performance prediction of the AN/APQ-159, airborne, F-5 radar. For this reason, quantitative measures of fading of target echoes were formulated. Probabilities of 10-percent fade and of triple miss are defined here, and algorithms, as well as some important general ...

Maximum Angular Accuracy of a Pulsed Search Radar

Proceedings of the IRE, 1956
An investigation is made of the limits imposed by receiver noise on the accuracy with which the angular position of a target can be determined by a pulsed search radar. Using a result in the theory of statistical estimation, a lower bound is derived for the standard deviation of regular unbiased estimates of target angular position, for a large class ...

Radar Navigation at Management Level (Radar, ARPA, Bridge Teamwork and Search and Rescue)

2019
This IMO model course addresses the competences and the training required for seafarers to maintain safe navigation through the use of information from navigation equipment and systems to assist command decision-making at the Management Level as specified in table A-II/2 of the STCW Code.

Searching for buried objects with surface penetrating radar

Proceedings The Institute of Electrical and Electronics Engineers. 29th Annual 1995 International Carnahan Conference on Security Technology, 2002
This paper reviews the principles of surface penetrating radar, discusses the technical requirements for the individual sub-systems comprising a surface penetrating radar and provides examples of typical applications for the method. Continued technical improvements in system performance enable clearer radar images of the internal structure of materials
