“…The polarisation parameter variance can be exploited. Polarisation filters are well studied and paid much attention, which are based on the orthogonal polarisation vector to the one of jammer [12–16]. Poelman and Guy [12] proposed a multinotch logic‐product polarisation suppression filter to suppress partly polarisational jamming and clutter.…”

Angle deception jamming makes the monopulse radar seeker track to itself but not the real target, which is catastrophic for the guidance radar. In this paper, an adaptive technique based on dual polarization radar is presented to counter it. How angle deception jamming acts on the monopulse tracking radar is first investigated. An angle estimation technique of the real target is then derived from the conventional monopulse method, although it is being interfered with by angle deception jamming. Meanwhile, the polarization ratio characteristic of the angle deception jamming could be adaptively estimated in current practical scene. Furthermore, the similar characteristic of Jones vectors is defined as the rule to judge whether the target is being interfered with by jamming. It can make the radar seeker select different techniques for angle estimation adaptively. Finally, two major factors of angle estimation accuracy are analyzed by simulation and the effectiveness of the proposed technique is proved through experiments.

“…By estimating polarization state of active jamming signal, polarization radar can greatly improve its electric counter countermeasures (ECCM) performance [4]. However, single polarzed radar does not own polarization information processing ability which restricted the application in polarization area.…”

Antenna polarization states always vary with scan direction which can be named as Spatial Polarization Characteristic (SPC) of antenna. We present a novel antenna module named orthogonal polarization binary array antenna (OPBAA). The advantage of the design is its simple design and prominent SPC. Which can be used for polarimetric application. The theoretical model is derived and spatial polarization characteristic is especially analyzed. Measurement results of an OPBAA formed by two horns are analyzed to verify the conclusions. The OPBAA can reduce the complexity of the communication system which has good application prospect in the future.
