I will do the simulation using MATLAB and I want to add the effect of channel as in communication into the model of the transmitted and the received signal in radar. the noise and the delay is already added
Noise and delay are two basic requirement of channel modelling in communication systems. I want to add a paper entitled "Channel characterization using radar for transmission of communication signals". Plz follow the link:
http://ieeexplore.ieee.org/document/4753823/
You will get lot of information on channel modeklling when multiple channels are being used. Here is the paper:
Digital equalisation in adaptive spatial filtering for radar systems: a survey
