摘要： This application describes techniques that mitigate the problems of range walk where fast moving objects are detected using pulsed target detection systems having relatively long dwell times. A pulse generator ( 102) for a pulsed target detection system (101 ) is disclosed which controls generation of a series of pulses (104) to be transmitted by the target detection system. The time between pulses and pulse characteristics are controlled such that any range migration due to target (107) movement in the time between pulses of said series is substantially equal and opposite to any variation in range-Doppler coupling between the pulses due to said target movement. By controlling the transmitted pulses in this way any potential variation in range cell due to target motion is offset by an equal and opposite variation in range- Doppler coupling, whatever the target radial velocity (
v ). The techniques are particularly applicable to radar systems.

摘要： A radar apparatus using a pulse compression technique, in which any automatic response signals are prevented from creating false radar images on the indicator screen of the radar apparatus.
An antenna repeats a transmit/receive cycle at a second time interval while rotating, in which i) a non-modulated pulse is transmitted, ii) a modulated pulse is transmitted a first time interval after the transmission of the non-modulated pulse, and iii) an echo and/or an automatic response signal occurring after the pulse transmission is received. For each transmit/receive cycle, a first separated receive signal having a frequency band corresponding to that of the modulated pulse and a second separated receive signal having a frequency band corresponding to that of the non-modulated pulse are separated. An elimination process is applied to the first separated receive signal, in which respective first separated receive signals for two consecutive transmit/receive cycles are compared and any signal component having discontinuity between two consecutive transmit/receive cycles is eliminated from the first separated receive signal. A pulse compression process is applied to the first separated receive signal having undergone the elimination process. The first separated receive signal having undergone the pulse compression process is combined with the second separated receive signal.

摘要： The invention refers to a secondary surveillance radar, referred to hereinafter as SSR, system (1) for air traffic control. The SSR-system (1) comprises a plurality of secondary radar stations (2) and is adapted for determining a location of an air traffic vehicle within the range of coverage of at least some of the secondary radar stations (2) by means of propagation time measurement of data signals (8) transmitted between the secondary radar stations (2) and a transponder (9) of the air traffic vehicle. Each of the secondary radar stations (2) works on a synchronized local time base. In order to provide for a high-precision synchronisation of the radar stations (2) of the SSR system (1) free of clusters, it is suggested that an SSR system's (1) secondary radar station (2) is synchronized depending on the content of synchronisation signals (10) received by the secondary radar station (2) to be synchronized and broadcast by one of the other secondary radar stations (2) of the SSR system (1). Preferably, the content comprises a time of transmission of the synchronisation signal (10).

摘要： In a homodyne-receiver radar system used for ranging and/or target detection, the frequency-modulated (FM) transmit phase is removed from the received signal (Rx). Removal of the known FM transmit phase from the received signal (110) reduces the bandwidth of the received signal to half that of a system that does not remove the transmit phase. This allows the sampling rate, and thus the processor throughput, to be cut in half. With the FM transmit phase removed, the phase sequence of the processed signal is akin to a delayed version of the transmit signal phase history. This allows the range processing to use segments of a single phase sequence for processing all range gates (112), resulting in a large reduction in the amount of coefficient storage used for the matched-phase sequences required to process the set of range gates.

摘要： An imaging radar system (10) comprising a forward-looking millimeter-wave radar system (10) for use in low visibility environments. The imaging radar system (10) comprises an antenna (11), a transceiver (12), a processor (13), and a display system (20). The transceiver (12) comprises a transmitter (14), a frequency reference unit (14a), and an RF receiver (15). The processor (13) comprises an IF receiver (16), an analog-to-digital converter (16a), a signal processor (17), a timing generator (18), input/output circuitry (18a) for interfacing with external systems (23, 24, 25), and a data processor (19). The display system (20) comprises a head-up or head-down display (21) and control circuitry (22). Several external systems (23, 24, 25) are coupled by way of the input/output circuitry (18a) to the data processor (19), including aircraft avionics, inertial reference, and data acquisition systems. Radar returns are amplified and downconverted to a lower intermediate frequency by the RF receiver (15) and downconverted to video frequencies in the IF receiver (16). The returns are sampled and digitized by the analog-to-digital converter (16a) and processed by the signal processor (17) using digital techniques to improve the range and azimuth resolution of the signal and provide corrections for geometry-dependent gain effects. The signal processor (17) transforms the data from range versus azimuth coordinates into azimuth versus elevation coordinates and sends the data to the display system (20) for display. The data processor (19) processes avionics data, inertial reference data, and system control signals from the external systems (23, 24, 25), and determines configuration and timing data for the system, and processing parameters for the signal processor (17).The data acquisition system (25) interacts with the signal and data processors (17, 19) to provide controls for testing and to receive data for storage. The present radar system (10) may be used for landing, takeoff, and taxi applications in low visibility environments.

摘要： A multipurpose system provides radar surveillance for air traffic control purposes. The system includes four separate active phased-array antennas, each with ± 45° coverage in azimuth, from 0° to 60° in elevation. Each antenna element of each phased-array antenna is coupled by a low-loss path to the solid-state amplifier associated with a transmit-receive (TR) module. Each antenna produces a sequence of pencil beams, which requires less transmitted power from the TR modules than a fan beam, but requires more time because the pencil beam must be sequenced to cover the same volume as the fan beam. In order to scan the volume in a short time, the PRF is responsive to the elevation angle of the beam, so higher elevation angles use a higher PRF. Low elevation angle beams receive long transmitter pulses for high power, and pulse compression is used to restore range resolution, but the long pulse results in a large minimum range within which targets cannot be detected. A second scan is provided at low elevation angles with a short transmitter pulse to fill in the short-range coverage. Beams at higher elevation angles transmit pulse widths which are shorter than beams at low elevation angles, so that the minimum range requirement is met without a second scan, which also reduces the time required for volumetric scan. The number of pulses which are integrated to produce a return increases off-axis, to restore system margin lost due to off-axis power gain reduction. The volumetric scan rate is increased by a dynamic scan regimen by which subsets of beams are pulsed with a high transmitter PRF but with a low effective beam PRF to reduce range ambiguity and preserve Doppler resolution without the usual increase of scan time. For best range resolution, Doppler processing is used, with range sidelobe pulse suppression applied separately to each Doppler frequency bin.
