“…As for the extraction of signal envelope and instantaneous phase, in the Channelized receiver it can be realized by the means of CORDIC algorithm in the vector mode. That is, according to I, Q from Channelized we solve the instantaneous phase ϕ(m) and signal envelope A(m), the relation formula will be [7,8] ϕ(m) = arctan Q(m) I(m)…”

The radar signal intercept problem under complex signal environment has been a research hotspot in the field of electronic reconnaissance. A kind of radar signal intercept receiver which has 500 MHz instantaneous bandwidth is proposed to receive multiple simultaneous radar signals and to give phase difference information to signal sorting. The channelized efficient architecture of odd arrangement is adopted and the parameters such as carrier frequency, pulse width, phase difference and so on are measured. The channelized efficient architecture of odd arrangement and the method of phase difference extraction are verified correct through computer simulation.

The fine frequency estimation of received signal is very important in Electronic Warfare and communication systems. The performance of radar classification depends on the accuracy of frequency measurements. Since frequency measurement accuracy in Digital Instantaneous Frequency Measurement receiver is highly dependent on corresponding pulse detection technique, here we propose an improved approach which is able to detect pulses as narrow as 50 nsec. Simulation results confirm that this receiver is capable of detecting pulses with 50 nsec width over 1.2 GHz bandwidth with a major error within 43 KHz.

At present, frequency (1) and phase are the most basic parameters in the measurement of electrical signal characteristics. A design of frequency and phase measurement system was proposed in this paper by using field-programmable gate array (2) (FPGA) and micro control unit (MCU).Our system consists of three modules: 1.Signal conditioning circuit module which is composed of wide-band channel amplifier and high-speed comparator; 2.Parameter measurement module; 3.Data display and control module. In addition, we implemented FPGA and MCU to realize duplex transmission of data through SPI communication interface.Our system designed in this paper can be used in a low and a medium speed measurement occasions. Based on the simulation result, a reasonable accuracy (3) was approached in our system.
