The Terminal Of Super Miniaturized Radar Reconnaissance And Its Signal Processing Technology

In recent years, the equipment of radar reconnaissance progressed to thecomprehensive, network and distributed. In this paper, a terminal of super miniaturizedradar reconnaissance which is used to distributed application is introduced. it has thenotable features of small size, low power consumption and shock vibration capability.The system consists of antenna, RF receiver unit, signal processing unit and thewireless communication link of four parts, where the signal processing unit is the coreof the equipment. This paper introduces the principle of radar reconnaissance systemand the main content, followed by the various units of the system a brief overview. Themain work of this paper is the deeply research of signal preprocessing algorithm andpulse de-interleaving algorithm, and the real-time radar pulse signal processing wasverified by the simulation. The signal preprocessing is achieved based on FPGA, thealgorithm of phase difference is used to detect the time domain parameters and thecarrier frequency of radar signal. The module of pulse de-interleaving is achieved basedon DSP, the algorithm of CDIF and SDIF is used, and it has correct real-timeperformance and detection accuracy.Finally, the result of equipment testing is given in this paper, the test resultsshowed that the system met the design requirements.
