| 摘 要： | 将目标的时频特征信息应用于毫米波辐射计对战术目标识别，Ｗｉｇｎｅｒ－Ｖｉｌｌｅ分布的全局矩用来作为目标特征系数．模拟结果表明，在一定信噪比范围内，这些目标特征系数有良好的稳定性，也说明了这一目标识别方法是切实可行的．

| Abstract: | Introduces the time-frequency characteristics to millimeter-wave radiometer system for tactical target recognition. Global moments of Wigner-Ville Distributions are adopted as the characteristic coefficients in target signature extracting. Simulation results show that those coefficients are robust under the given SNR range, and the corresponding approach of target recognition is feasible. |
