Abstract

The integrated design method of the millimeter-wave (Ka band) microstrip monopulse antenna array and infrared dual-sensor system is presented in this paper. The performance and structure of the sensor are optimized. Meanwhile, the simulated and measured results of the circular planar antenna with a IR aperture are also demonstrated, meanwhile the result improves that the infrared sensor also has effect upon the antenna array.

Abstract

It is shown in this paper that in geometrical space two polarization planes of the linearly polarized light waves scattered by particles in measuring ellipsoid constitute an angle of π/2. while in sequence of time the signals sent out by two symmetric pholodetectors in PLDA are separated by a phase angle π. This property of PLDA enables the improvement of SNR.
