Abstract

A statistical study of the effectiveness of the non-threshold search procedure for a noise-like phase-shift keyed signal by the delay time is carried out during observation against the background of noise and single-tone continuous wave interference for various options for its frequency position. The formation of the output effect of the search procedure due to the transition to the frequency domain using the discrete Fourier transform is considered. Families of dependences of the probability of correct search performance on the dimensionless frequency detuning are obtained for various “interference/signal” (jam-to-signal) ratios. A significant variation of the permissible level of energy superiority of interference over the signal is shown at which the value of the selected quality indicator is preserved. Quantitative and qualitative conclusions are made about the effect of single-tone continuous wave interference on the efficiency of the non-threshold search procedure.

连续波干扰对频域转换延迟时间对类噪声信号的非阈值搜索过程效率的影响

摘要

在噪声和单音连续波干扰的背景下，针对其频率的各种选择，在观察期间对类噪声相移键控信号的非阈值搜索过程的有效性进行了统计研究。位置。考虑了由于使用离散傅里叶变换转换到频域而导致的搜索过程的输出效应的形成。对于各种“干扰/信号”（干扰信号）比率，获得了正确搜索性能的概率对无量纲频率失谐的依赖关系族。显示了对信号的干扰能量优势的允许水平的显着变化，在该变化处选择的质量指标的值被保留。
