针对强噪声背景中弱信号检测问题，在传统检测方法基础上，提出了基于联合去噪和频率调制的微弱信号检测方法。搭建自相关和小波阈值变换联合去噪系统，极大程度抑制了噪声对检测结果的不利影响。利用频率可调标准信号调制待测信号频率，使得被测信号与检测系统策动力信号的频率差满足检测条件，打破了利用Ｄｕｆｆｉｎｇ 振子检测系统只能检测与系统策动力频率相近信号的限制。(In order to solve the problem of weak signal detection in strong noise background, based on traditional detection methods, puts forward the method of weak signal detection and denoising based on frequency modulation. The self correlation and wavelet threshold transform combined de-noising system can greatly restrain the adverse effect of noise on the detection results. Use adjustable standard signal modulation signal frequency to be measured frequency, the signal detection system and the driving signal frequency difference meet the test conditions, the system can only break detection signal detection and system driving the similar frequency limit by using Duffing oscillator.)

AM RECEIVER based on super heterodyne principle virtually used in all modern radio and television receivers. The approach mainly involves the use of heterodyning or frequency mixing. The signal from the antenna is filtered sufficiently at least to reject the image frequency and possibly amplified. A local oscillator in the receiver produces a sine wave which mixes with that signal, shifting it to a specific intermediate frequency (IF), usually a lower frequency. The IF signals is itself filtered and amplified and possibly processed in additional ways. The demodulator uses the IF signals rather than the original radio frequency to recreate a copy of the original modulation (such as audio). The project is coded in MATLAB.
