Research on Signal Processing Method of X-band Multifunctional Phased Array Radar

The signal processing algorithm is an important component of the three major technical fields of radar, and it occupies an important position in the radar system. It is the basis for phased array radar to achieve multi-function. The rapid development of modern signal processing technology has greatly promoted the development and application of radar technology. Modern radar simulation systems can simulate and optimize signal processing algorithms, and quickly adjust system parameters; because it adopts modularization and systematically encapsulated, it can be used repeatedly in different environments or platforms. The continuous development of modern signal processing technology has improved the performance of the radar system, especially in improving the radar's target detection capability and anti-jamming performance. Because signal processing occupies a very important position in radar systems, this paper studies the signal processing in radar systems. This paper analyzes the signal processing process of the multifunctional phased array radar, and conducts corresponding analysis and research on the key technologies.

Optical signal processing in Radar systems

Opto-electronic components and their performances are well suited to be integrated in radar systems. In this paper, two optical architectures illustrate functions that are specific to optical processing of microwave signals, i.e., time-delay-based processing and arbitrary waveform generation of large frequency bandwidth signals.

Wireless identification and sensing using surface acoustic wave devices

Today Surface Acoustic Wave (SAW) devices are used in many electronic products, e.g. as filters in communications applications or for signal processing in radar systems. Due to the dependence of the propagation characteristic of the microacoustic wave on many physical parameters (e.g. temperature or strain) it is possible to build SAW sensors for a great variety of physical, chemical and biological parameters. SAW sensors are not only small, rugged and show small aging rates, they also can be used as wirelessly interrogable and completely passive sensors for many hostile environments. In this contribution the SAW device principles, design procedures and technological issues as well as examples of their use in certain measurement and identification applications are reviewed.

Special-purpose computer for video signal processing in radar systems

A special-purpose computer for processing video signals in radar systems is presented. The main part of the computer is an array of Q processing elements (PEs), all driven by the same microprogrammed control block. Each PE handles four bits in parallel, and carries out arithmetic and logic operations on operands from 4–16 bits long. It contains a local memory and an unconventional microprocessor designed to be custom integrated on a 40-pin chip. A set of problem-oriented instructions has been defined, giving efficient implementation of algorithms used in radar computations. The computer can assume different configurations, making it suitable for a large class of radar systems.
