Radar Range Equation and Timing.
A radar has the following design parameters:
Pt = 6 kW
Gt = 36 dB
Fc = 5 GHz
Noise Figure = 8 dB
System Temperature = 290K
PRF = 1500 Hz
Bandwidth = 1 MHz
Azimuth Beamwidth = 1.5 deg
Scan Rate = 60 RPM
a. For a stationary target with a RCS of 5 m2 located 8 nmi away from the radar, compute the expected radar received power in dBm (dBmilliWatts). Perform this calculation both using the linear (multiplicative) form of the radar range equation and the decibel (additive) form. (Read Module 2B again for additional help.) Convert all units as needed and demonstrate all dimensional units are accounted for. Verify that the Pr computed with the multiplicative equation is the same as the Pr computed with the decibel equation.
c) For the target described in Problem 1a, compute the corresponding fast (short) time at which the reflected waveform is expected to appear within the received signal, assuming each PRI starts at tfast = 0 and ends at tfast = 1/PRF.
Solve part c.
