기존의 적응형 배열 안테나 처리는 모든 배열 안테나 요소의 신호에 액세스해야 합니다. 그러나 저가형 ESPAR(Electronically Stereable Passive Array Radiator) 안테나는 단일 포트 출력만 있기 때문에 안테나 요소의 모든 신호를 관찰할 수 없습니다. 본 논문에서는 수동 방사체에 부하된 리액턴스를 적응적으로 제어하여 빔과 널을 모두 형성하는 ESPAR 안테나에 대한 기술을 제시합니다. 적응형 알고리즘은 경사 벡터를 결정하기 위해 리액턴스가 순차적으로 교란되는 가장 가파른 경사 이론을 기반으로 합니다. 시뮬레이션에 따르면 ESPAR 안테나는 적응형일 수 있습니다. ESPAR 안테나 출력 SIR의 통계적 성능도 제공됩니다.

Jun CHENG, Yukihiro KAMIYA, Takashi OHIRA, "Adaptive Beamforming of ESPAR Antenna Based on Steepest Gradient Algorithm" in IEICE TRANSACTIONS on Communications,
vol. E84-B, no. 7, pp. 1790-1800, July 2001, doi: .
Abstract: Conventional adaptive array antenna processing must access signals on all of the array antenna elements. However, because the low-cost electronically steerable passive array radiator (ESPAR) antenna only has a single-port output, all of the signals on the antenna elements cannot be observed. In this paper, a technique for adaptively controlling the loaded reactances on the passive radiators, thus forming both beam and nulls, is presented for the ESPAR antenna. The adaptive algorithm is based on the steepest gradient theory, where the reactances are sequentially perturbed to determine the gradient vector. Simulations show that the ESPAR antenna can be adaptive. The statistical performance of the output SIR of the ESPAR antenna is also given.
