Abstract:

By analyzing the basic characteristics of spaceborne applications,a finding method with phase interferometer of four antenna cruciform array is proposed.From a single station passive location departure,the time difference of arrival angle signals between three interferometers relative to a reference interferometer are analyzed with three signal phases obtained.But the actual value of the phase difference measurement interferometer is blurred.A signal simulator software design is proposed,which interacts with DSP via the USB,and transmits the data of all pulses when the aerial platform passes a target.

Key words: cruciform array;phase interferometer;signal phase;signal simulator software
