Recent developments in airborne magnetic detection systems have made it possible to detect much small magnetic objects such as unexploded ordnance. However, the data sets are extremely large and the measurements must be processed and interpreted. Therefore, there is an increasing need for a fully automatic processing and interpretation techniques that can be used to make decisions regarding the nature of the source in real time. So, the aim of the present paper is to shed further light on the real time correction of parallax/Lag -and air-condition-noises in airborne magnetic data acquisition. A novel electronic technique, based on micro-controllers design and implementation, was designated for real-time processing applications. The proposed technique shows excellent airborne magnetic data results considering actual field examples. The proposed technique verifies an accurate and objective tool for magnetic objects detection compared with the existing PEI tools considering cost and processing automation capabilities.

The present paper reports on a trial to shed further light on the characterization, applications, and operation of radar speed guns or Gunn diodes on different radiation environments of neutron or g fields. To this end, theoretical and experimental investigations of microwave oscillating system for outer-space applications were carried out. Radiation effects on the transient parameters and electrical properties of the proposed devices have been studied in detail with the application of computer programming. Also, the oscillation parameters, power characteristics, and bias current were plotted under the influence of different g and neutron irradiation levels. Finally, shelf or oven annealing processes were shown to be satisfactory techniques to recover the initial characteristics of the irradiated devices.
