Single-station pulse RCS (Radar Cross Section) testing system based on switch shifting

Abstract

The invention provides a single-station pulse RCS (Radar Cross Section) testing system based on switch switching. The single-station pulse RCS testing system comprises a main control computer, a transmitter, a receiving-transmitting switch, a receiver, a multipath pulse generator and a receiving-transmitting antenna, wherein the main control computer is used for setting the parameters of the transmitter according to measured parameters, and setting the parameters of the receiver and the parameters of the multipath pulse generator at the same time; the transmitter comprises a transmitting source and a pulse modulator; the multipath pulse generator is used for generating a first pulse baseband signal, and transmitting to the control end of the pulse modulator; the multipath pulse generator is used for generating a second pulse baseband signal, and transmitting to the control end of the receiving-transmitting switch; the receiving-transmitting antenna is used for receiving an echo signal of a tested target; the echo signal is transmitted to the receiver after passing through the third pin of the receiving-transmitting switch; and the receiver is used for processing the echo characteristic of the tested target, and transmitting to the main control computer.

Description

technical field [0001] The invention relates to the field of radar, in particular to a switch-based single-station pulse RCS test system. Background technique [0002] Radar cross section (RCS) is a physical quantity that quantitatively characterizes the intensity of the target's scattering of radar radiation waves. With the rapid development of electronic warfare, the large-scale use of stealth weapons has become a prominent feature of modern warfare. Stealth technology can effectively increase the distance that radar can detect targets, and becomes an important means to enhance assault capabilities or protect oneself. The stealth performance of a target mainly depends on the size of its RCS, so reducing the radar cross section by various methods has become the main goal of researching stealth technology. This requires RCS testing of various targets. Since the RCS characteristics of the target are for the radar, the RCS test should also try to simulate the working mode o...
