This chapter introduces a design case study, referred as "Textbook Radar". The radar design case study "Textbook Radar" is a ground-based air defense radar based on E. Brookner's open literature source. However, the design process takes on a different flavor than that introduced by Brookner. The major characteristics of radar waveforms include the waveform's energy, range resolution, and Doppler resolution. The choice of an operating frequency that can fulfill the design requirements is driven by many factors, such as aperture size, antenna gain, clutter, atmospheric attenuation and the maximum peak power, to name a few. Modify the "Textbook Radar" design case study so that the effects of target Radar cross section (RCS) fluctuations are taken into account. The single frame probability of detection can be improved significantly when pulse integration is utilized. One may use coherent or non-coherent integration to improve the frame cumulative probability of detection.
