Problems solved by technology

In the past, the test was mainly carried out on-site in the field. Due to the weather environment and the cost of manpower and material resources, and the external environment will also have a great impact on the performance test of the signal processor, it is easy to cause errors, resulting in There are inevitable hidden dangers in the test in the real environment, so the development of the radar echo simulator is very important

Abstract

The invention discloses an array radar simulator. The array radar simulator includes a main board, an interface board and a storage board; the main board is used for obtaining a FLASH erasing instruction, a FLASH writing instruction and a FLASH reading instruction, and receiving and sending array radar echo signals in real time, wherein the array radar echo signals are sent by the interface board; the interface board is used for successively receiving the FLASH erasing instruction, the FLASH writing instruction and the FLASH reading instruction, and obtaining the array radar echo signals in real time, so as to obtain low-electric level FLASH erasing gating signals, low-electric level FLASH writing gating signals and low-electric level FLASH reading gating signals, and then converting the array radar echo signals into N channels of cache array radar echo signals; the storage board is used for receiving and storing the N channels of cache array radar echo signals, the low-electric level FLASH erasing gating signals, the low-electric level FLASH writing gating signals and the low-electric level FLASH reading gating signals in real time, sequentially carrying out FLASH erasing, FLASH writing and FLASH reading operation, sequentially obtaining a FLASH erasing completion instruction, a FLASH writing completion instruction, a FLASH reading completion instruction and N channels of cache FLASH array radar echo signals, and storing the FLASH erasing completion instruction, the FLASH writing completion instruction, the FLASH reading completion instruction and the N channels of cache FLASH array radar echo signals in real time.

Description

technical field [0001] The invention belongs to the technical field of radar echo simulation, in particular to an array radar echo simulator and a simulation method thereof, which are suitable for practical engineering applications. Background technique [0002] With the rapid development of science and technology, the requirements for radar detection are also increasing. Modern radars need to have higher search speed, resolution and anti-interference ability. Traditional radars use mechanical scanning, which is costly and takes a long time to scan. In order to solve this drawback, electronic scanning radars have been developed. Array radar is an electronic scanning radar. It can form beams with different characteristics, and can change the beam direction by controlling the phase and amplitude of each array element of the antenna. Its scan time is short and easy to control, and if a front antenna is used, the antennas can be grouped to achieve different functions, that is, ...
