Question

A surface search radar has the following characteristics:
i. Frequency = 5 GHz (C-Band - vertical polarization)
ii. Peak power = 5 kW
iii. Circular phased-array – diameter = 1.00 meters
iv. Noise Figure = 2 dB
v. Total System Losses = 10 dB
vi. Duty factor = 5%
vii. Dwell length or processing time = 1.0 ms
viii. Bandwidth = 1 MHz

Using Matlab 
Plot the SNR (in dB, y-axis) versus Range (from 1 km to 50 km) for a target with a 1
m2 RCS. Assume maximum antenna gain towards the target, antenna gain is the same for
transmit and receive, and unity propagation. If a SNR of 15 dB is required to detect the target, at
what range is the target first detectable?
