Abstract

The present application relates to a kind of radar infrared integrated transmitting receiving board, including main control processing module, multi-dimensional coding transmitting module and joint receiving demodulation module.Main control module generates composite timing instruction package according to preset parameter, and generates chaotic sequence based on Logistic chaos model, and accordingly produces chaotic modulation radar signal and infrared digital pulse signal.Transmitting module uses the signal to drive radar antenna and infrared transmitting tube respectively according to specified timing signal emission.Signal is received synchronously by receiving module radar and infrared mixed return signal, and according to instruction package timing sampling is mixed digital signal;Then carry out time domain cross-correlation operation, obtain radar and infrared correlation function set.Main control module is positioned again through correlation peak detection, and separates radar and infrared return signal in mixed signal.The present application uses chaotic multi-dimensional coding to improve interference immunity, and effectively separates signal by joint receiving demodulation, significantly enhances the system comprehensive detection performance.
