The traditional radar signal processor have a poor performance in scalability and universality. To solve this problem, this paper proposes a new kind of radar signal processing system architecture based on crosspoint switch. A radar signal processor is usually composed of multiple circuit boards .The crosspoint switch is able to make circuit boards connection dynamically. The connections of channels between boards can be one channel to another, one channel to several channels or several channels to one channel. A single signal processing circuit board also has the characteristics of scalability and universality. Eight general digital signal processing chips(ADSP-TS201) form a cubelike network which can be constructed a variety of parallel signal processing systems. Data transmission rate between boards can reach 18.75Gbit/s(3.125*6). The internal processing speed of each signal processing board reaches 4.8G(600M*8) times per second. It meets the needs of high speed real-time computing.
