Problems solved by technology

However, this processing method cannot eliminate the scattered signals that reach the receiving antenna at the same time as the scattered signals in the darkroom and the target to be measured. The distance sum is the same as the distance from the transmitting antenna to the target to be measured and the distance from the target to the receiving antenna is equal, then these unwanted scattered signals will also fall into the rectangular box in Figure b, and arrive at the receiver at the same time as the target signal to be measured antenna, it will be difficult to eliminate the

Abstract

The invention discloses a synchronous scattering point area determination method for double-station radar target property measurement. The synchronous scattering point area determination method comprises the following steps: establishing a three-dimensional rectangular coordinate system in a darkroom; determining the positions of a transmitting antenna and a receiving antenna in the three-dimensional rectangular coordinate system; using the positions of the transmitting antenna and the receiving antenna as focal points; respectively using the maximum and the minimum of the sum of distance from any point in the testing area to the transmitting antenna and distance from any point in the testing area to the receiving antenna as the long axis lengths of ellipse, and constructing two ellipsoids in the darkroom; obtaining the synchronous scattering point area defined by the two ellipsoids and the space between the two ellipsoids. The method can be used for quickly finding the synchronous scattering point maximal area where the sum of the distance from the transmitting antenna in the darkroom to the synchronous scattering point position and the distance from the synchronous scattering point position to the receiving antenna is equal to the sum of the distance from the transmitting antenna to an object to be tested and the distance from the object to be tested to the receiving antenna.

Description

technical field [0001] The invention relates to a method for determining the area of ​​a scattering point. More specifically, it relates to a method for determining the area of ​​a scatter point synchronously for bistatic radar target characteristic measurement. Background technique [0002] With the development of stealth and anti-stealth technology, more and more scientific and technical personnel are concerned about the bistatic scattering characteristics of radar targets. Schematic diagram of indoor dual-station radar target characteristic measurement as shown in figure 1 As shown, the dual-station measurement means that the transmitting antenna and the receiving antenna are not in the same position, and have a certain dual-station angle relative to the target to be measured. The electromagnetic wave reaches the target to be measured, and the scattered electromagnetic wave of the target to be measured is received by the receiving antenna in another direction. [0003]...
