Range-dependent eclipsing factor
Description
Examples
Calculate and Plot Range-Dependent Eclipsing Factor
Calculate the range-dependent eclipsing factor at 1
km intervals between zero and the unambiguous range, R
, assuming an unmodulated rectangular pulse with a duty cycle of 0.1
and the pulse repetition frequency of 1000
Hz.
DU = 0.1; PRF = 1e3; R = 0:1000:time2range(1/PRF); FECL = eclipsingfactor(R,DU,PRF);
Plot the range-dependent eclipsing factor.
plot(R*1e-3,FECL) xlabel('Range (km)'); ylabel('Eclipsing Factor (dB)'); ylim([-25 1]); grid on; title('Range-Dependent Eclipsing Factor');
Input Arguments
R
— Range at which to compute eclipsing factor
positive scalar | length-J
vector
Range at which to compute the eclipsing factor, specified as a positive scalar or as a length-J vector in meters.
DU
— Duty cycle
nonnegative scalar | length-M
vector
Duty cycle, specified as a nonnegative scalar in the range [0,1]
or length-M vector with each element in the range
[0,1]
.
If you specify
DU
as a scalar, the eclipsing factor is computed for an unmodulated rectangular pulse with the specified duty cycle.If you specify
DU
as a length-M vector, the eclipsing factor is computed for a waveform, using time domain samples taken over a one-pulse interval.
PRF
— Pulse repetition frequency
positive scalar | length-K
vector
Pulse repetition frequency, specified as a positive scalar or as a length-K vector in Hz.
