摘要： Techniques are disclosed for detection and ranging systems and methods to improve range resolution, target separation, and reliability. A method includes selectively attenuating a signal representing a ranging system return or echo from targets so as to suppress side lobes or other undesirable artifacts appearing in the signal due to noise, interference, and/or distortion. A method may additionally or alternatively include rejecting interference events in ranging system returns by comparing a received return with that expected from a target illuminated by the ranging system, as determined by characteristics of its particular ranging sensor, and rejecting or attenuating returns or portions of returns that fail to match those characteristics in time or space. A system configured to perform such methods and comprising a transducer/antenna, a transceiver, a controller, and/or other logic devices implementing a pulse generator, correlator, selective attenuator, comparator, buffer, subtractor, and/or output circuit is also disclosed.

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 are removed from the received signal. Removal of the known FM transmit phase from the received signal 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, 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.
