Analysis and Simulation of Multi-target Echo Signals from a Phased Array Radar

Abstract

The construction of digital radar simulation systems has been a research hotspot of the radar field. This paper focuses on theoretical analysis and simulation of multi-target echo signals produced in a phased array radar system, and constructs an array antenna element and a signal generation environment. The antenna element is able to simulate planar arrays and optimizes these arrays by adding window functions. And the signal environment can model and simulate radar transmission signals, radar internal noise, clutter and jamming signals. These signals are combined linearly to generate the radar echo signal. The simulation results indicate that multi-target echo signals are completely overwhelmed by other signals, satisfying the needs of subsequent signal processing and data processing
