If a radar system using Swerling I wishes to detect an aircraft at a maximum range of 100 km with a required detection probability of 0.9, calculate the implications on transmitted power needed versus a non-fluctuating target.
💡 Hint: Consider the relationship between SNR and power needed for detection based on fluctuation models.
A radar system must adapt its parameters for detecting a target transitioning from Swerling IV to Swerling I. What changes should be made in terms of SNR and sensitivity?
💡 Hint: Evaluate how average RCS changes impact required sensitivity for different models.
