8.7.1. Problem Statement

Modify the ÐMyRadarÑ design case study such that we employ a phased
array antenna. For this purpose, modify the design requirements such that the
search volume is now defined by and . Assume X-band, if
possible. Design an electronically steered radar (ESR). Non-coherent integra-
tion of a few pulses may be used, if necessary. Size the radar so that it can ful-
fill this mission. Calculate the antenna gain, aperture size, missile and aircraft
detection range, number of elements in the array, etc. All other design require-
ments are as defined in the previous chapters.
