3. A radar is attempting to detect a point target in the presence of ground clutter. The parameters of the radar and its environment are such that the SNR at a range of Ro = 10 km is 30 dB, while the SCR at the same range is 20 dB. The detection performance at this range is “clutter limited" because the clutter is the dominant interference. Assume the clutter interference is pulse-limited and that oº does not vary with range. At what range will the SNR and SCR be equal? (At ranges longer than this, the detection performance for this target will be “noise limited.")
