“…Assume that all enemy targets within a certain area fly to the center of the area, and the altitudes of the early warning radar and enemy target are constant. The distance between the enemy target and early warning radar is a, b is the distance from the enemy target to regional center, and the distance between the regional center and the early warning radar is c. Thus, the cosine of the angle α can be calculated by (2) Thus, the Doppler frequency shift of the enemy target with respect with the early warning radar is (3) VT is the relative velocity of the enemy target with respect to early warning radar, λ is the wave length.…”

Abstract. Early warning radar is able to effectively detect the target utilizing Doppler Effects between the target and radar. The detection effectiveness of the airborne early warning radar is affected by its detection range as well as its detection probability. In this paper, a method for simulating the detection effectiveness of the airborne early warning radar is proposed. First, the detection model of the airborne early warning radar is designed. And then, based on the motion parameters of the airplane and target as well as the radar system parameter, the detection effectiveness of the early warning radar is simulated and displayed dynamically. Finally, the detection effectiveness of the early warning radar is validated. Simulation results show that the proposed method can effectively simulate the detection effectiveness of the airborne early warning radar, and has the friendly man-machine conversation.

“…If the bistatic SAR system includes more than one receivers or transmitters, the scene can be illuminated at the different angles, which can acquire the increased information of the targets. The one-stationary bistatic SAR is a special bistatic SAR system [11] [12] [13], which has a moving transmitter (receiver) and a stationary transmitter (receiver). One-stationary bistatic SAR system not only inherits the advantages of the general bistatic SAR system, but also is easy to build and implement imaging, thus it has attracted the wide attention.…”

Low frequency ultrawideband (LF UWB) synthetic aperture radar (SAR) has lately become of a particular interest to SAR community. Monostatic and bistatic LF UWB SAR system has the well foliage penetrating capability, high-resolution imaging and providing the increased information. In 2015, a monostatic and bistatic LF UWB SAR imaging experiment was conducted. In this experiment, the monostatic and bistatic data were collected simultaneously by operating a moving vehicle-based radar in the SAR mode, in conjunction with a stationary ground-based receiver. The aim was to investigate the imaging property of the bistatic LF UWB SAR system. The one pulse per second (1 PPS) signal in combination with the global position system (GPS) disciplined 100 MHz oscillator from the GPS receivers was used to implement the time and frequency synchronization in this SAR system. The bistatic SAR image was obtained by the subaperture spectrum-equilibrium method integrated with the fast factorized back projection (FFBP) algorithm. Bistatic experiment results are show to prove the validity of the bistatic LF UWB SAR imaging experiment.

“…If BSAR system includes more than one receivers or transmitters, the imaging scene can be illuminated at different angles, which can acquire the added information of scenes. One-stationary BSAR (OS-BSAR) is an azimuth variant BSAR system [11], [12], which has a moving transmitter or receiver and a stationary receiver or transmitter fixed at a high position. OS-BSAR not only inherits the advantages of the general BSAR, but also is easy to implement imaging, thus it has attracted the much attention.…”

 Low Frequency Ultrawideband Bistatic Synthetic Aperture Radar (LF UWB BSAR) can produce the higher resolution image and obtain the added information of scenes. In the paper, a vehicle experiment of the LF UWB BSAR is described and the result is proposed. This BSAR system has a LF UWB SAR system as the vehicle-based transmitter and the other LF UWB radar system as a ground-based receiver. In August 2015, the vehicle experiment was conducted in Changsha in China, and the LF UWB BSAR raw data was collected. The aim was to investigate the imaging property of the LF UWB BSAR system. 1-PPS signal in combination with the Global Position System (GPS) disciplined 100MHz oscillator from GPS receivers were used to implement the time/frequency synchronization of LF UWB BSAR systems. Bistatic image was obtained using the subaperture spectrum equilibrium method integrated with the Fast Factorized Back Projection (FFBP) algorithm. Excellent results prove the validity of the vehicle experiment of the LF UWB BSAR.
