A portable compact target motion simulation system, adapted to generate simulated target motion for displaying, tracking, and controlling a plurality of simulated targets on a display device for training purposes. The system is operable to generate pre-programmed and dynamic exercises, for training trainees in operating tracking devices, to develop trainee skill in analyzing and responding properly to target motion. The apparatus is totally programmable, and capable of providing targets in any matrix. It includes a target display generator, adapted to store, merge, and transmit timed data signals for driving a target-display device. It further includes a dynamic target motion generator, microprocessor-based, adapted to receive input data identifying the characteristics of particular operator-controlled targets and convert such data into dynamic target motion input data for driving the target display generator. A remote input device, microprocessor-based, enables the operator to interface with and control the functions of particular targets in the target display generator, by inputting target motion initiation and modification data into the dynamic target motion generator, for generating a display to train the trainee. The apparatus further includes a pre-programmed target motion generator, microprocessor-based, operable in conjunction with a data storage and retrieval device, to generate pre-programmed target motion for demonstrating certain target motion functions, or as a background for dynamic target motion for driving the target display generator, or to store data from the pre-programmed target motion generator and dynamic target motion generator after display thereof, for subsequent debriefing purposes.
The radar target simulator serves for the training of air traffic controllers. It comprises a radar device (10) detecting the approach area of a runway, and a display device (17) for displaying the real targets detected by the radar device (10). The display device generates an approach line corresponding to an ideal approach. The instructor position comprises a simulation device (18) for generating simulation targets moving continuously depending on flight parameters of a simulated airplane, which have been inputted. The real targets detected by the radar device (10) and the simulation targets are displayed together on the display device (17). The simulation device (18) is used to check the correctness of the adjustment of the radar device (10). Therefore, an airplane performing an ideal approach is simulated on the display device (17) and it is detected whether there are any deviations of the simulation target from the approach line displayed on the display device. Thereby, the efforts for monitoring and checking the radar device are substantially reduced.
A low cost simulator for training electronic warfare operators to recognize signatures of various emitters. The simulator consists of a card which can be plugged into an IBM PC or compatible computer. Through the computer, various characteristics of one, or a plurality of emitters are entered. The simulator, using an existing digital signal processing (DSP) chip generates a replica of a signal received by a radar system receiver from one, or a plurality of emitters.
A portable radar simulator which when connected to a transmitting means s as a magnetron generated microwave threat transmitter simulates up to 2048 pre-programmed radar signatures. The portable radar simulator comprises a replaceable Erasable Programmable Read Only Memory (EPROM) which will hold up to 2048 pre-programmed radar signatures. Selection of a particular radar threat to be simulated is entered by an operator via thumbwheel switches located on the front panel of the simulator. The portable radar simulator simulates such radar parameters as jitter, stagger, frequency hop, simple and complex scans, pulse repetition intervals and frequency pulse widths.
A moving target simulator for testing a radar system has a radio frequency receiver, a digital radio frequency memory in electrical communication with the radio frequency receiver for storing a signal received thereby, a digital delay circuit in electrical communication with the digital radio frequency memory for providing a time delay between reception and transmission of the radio frequency signal, an amplitude modulation circuit in electrical communication with the digital radio frequency memory for modulating an amplitude of the radio frequency signal, a Doppler modulation circuit in electrical communication with the digital radio frequency memory for providing a Doppler-modulated signal, and a radio frequency transmitter for transmitting the radio frequency signal after it has been delayed, amplitude-modulated, and/or Doppler-modulated.
