// Given Data
PW = 10^-6; // Pulse width in sec
Pp = 100*10^3; // Peak power in watts
PRF = 1000; // pulse rep.rate
N_target= 20; // no of target hits in 1 dwell period
// Calculations
PE = Pp*PW; // Pulse energy in Joule
LE = N_target *PE; // look energy
DC = PW*PRF // Duty cycle
Pav = Pp*DC; // Average power
Pavg = 10*log10(Pav); // Avg power in dB
Pp_dB = 10*log10(Pp); // Peak power in dB
DCCF = Pp_dB - Pavg // Duty cycle correction factor
// Output
mprintf('Duty cycle correction factor = %d dB',DCCF);
