We have developed improved versions of three different radar systems and integrated them as an airborne instrumentation suite for sounding and imaging Polar ice sheets. The first instrument consists of a multi-channel, coherent, pulsed radar operating at VHF with up to 20 MHz bandwidth. This instrument is capable of sounding a few-kilometer thick ice while flying at altitudes up to 10 km above mean...
A study of numerical integration methods suitable for antenna pattern calculations was conducted for the purpose of determining which method provides a given accuracy with the greatest economy. The accuracy for a given method depends on the number of points at which the integrand is calculated, while the cost for a given number of points depends on the complexity of the method. This paper discusses...
