峰值半宽度 meaning in English

peak half width

This paper analyzed the modulation and filter technique on joint power spectrum ( jps ) , which reduced the intensity and width of the strong dc component existing in the classical joint transform correlator , improved the recognition ability greatly
针对联合变换相关器，分析了对联合功率谱的调制和滤波技术，缩小了峰值半宽度、削弱了零级自相关的能量，改善了经典联合变换相关器识别性能。
