Design For Signal Processor Of ARM Seeker

The Anti-Radiation-Missile (ARM) is an important lethal weapon in the electronic war. It can destroy the enemy radars effectively. The Anti-Radiation-Missile-Seeker (ARMS) is a key component of the ARM. The capability of the ARMS directly influences the performance of the ARM.Anti-Radiation-Missile seeker is a passive angular tracker, which consist of a monopulse radar receiver and a signal sorting and identification processor. The monopulse radar receiver is used to track the desired target and the processor to separate and directs the seeker to the target in multiple signal environment.The implement of the sorting and identification processor is the aim of this paper. The input of the processor is the frequency code and the video pulse. With the measured data such as time of arrival(TOA)> width > repetition frequency(RF) and amplitude of every pulse and the frequency code the processor can sort the signal and identification the desired radar. According with the measured radar frequency the processor locks the tracker receiver's frequency into that of the tracked radar, it also output the TOA information of pulse to turn on the tracker receiver so that the tracker receiver can track the desired radar. The another function of the processor is to estimate the arrival angle of every jammer by processing the angle error information from the receiver and make the seeker track only one jammer with the angle filter technique when the seeker operates in the multiple C W jammers scenario.The aim of this paper is focused on the implementation of the signal processor of the Anti-Radiation-Missile seeker. A high speed fixed point DSP?TI's TMS320C6201 has been used in this project. Its performance of high speed and precise can fit the ARM's need for real-time processing. It has been used mostly in signal sorting, identification and angle separation. Another processor, ALTERA'sEPM3256AQC208-10 is used to measure the pulse parameter ,collect data and generate relative output signals.
