Embodiment Construction
[0021] The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0022] Such as figure 1 As shown, a broadband chaotic radar system based on an optical analog correlation receiver includes a signal transmitter, a signal receiver and a broadband antenna.
[0023] Described signal transmitter produces chaotic signal (-10dB bandwidth is greater than 500MHz) by broadband chaotic signal source 1, and chaotic signal input peak-to-average power ratio adjuster 2 carries out peak-to-average power ratio adjustment, and the output signal of peak-to-average power ratio adjuster 2 is passed through The first broadband power splitter 3a is divided into two paths: one path is used as the reference signal S after being delayed by the first electrical delay line 8 and attenuated by the programmable attenuator 9 1 (t); the other way is used as a detection signal, mixed with a high-frequency sinusoidal signal generat...
